  • TITANIUM SHEET/PLATE

    Titanium

    plate
    and sheet are commonly used in manufacturing today, with the most popular

    grades being 2 and 5.

    Grade 2 Titanium

    Grade 2 is the commercially pure titanium used in most of the chemical

    processing plants and is cold formable. Grade 2 plate and sheet can have ultimate

    tensile strength at and above 40,000 psi.

    Grade 5 Titanium

    Grade 5 is the aerospace grade and is not cold formable, so it is used more

    often when no forming is needed. Grade 5 aerospace alloy will have ultimate tensile

    strength at and above 120,000 psi.


    Plate is often used with the goal to get really close to the final

    dimensions of the part being made. The material is worked to the closest size of the

    desired part and the grain structure of the finished piece is more homogenous. Titanium

    sheet is often used as a heat barrier because titanium stops the heat and does not

    transfer to the rest of the assembly. Titanium plate and sheet have ballistic properties

    making it great for driver protection in racing.

    Roller Expansion


    The most commonly used method of making tube/tube sheet joints is roller expansion.


    Roller expansion procedures for titanium tube into tube sheets are similar to those used

    for other materials. For best results, the tube sheet holes should be within the limits

    specified by TEMA (Tubular Exchanger Manufacturers Association) for shell and tube heat

    exchangers or within the limits specified by HEI (Heat Exchange Institute) Standards for

    Steam Surface Condensers.


    Determining Expansion


    There are three commonly used methods of determining the correct amount of

    expansion:


    1. Measuring wall reduction


    2. Simulating wall reduction by interference


    3. Pull-out strength versus torque curve


    The above pull-out test is preferable. The suggested wall reduction for titanium

    tubes is 10%. Thus, in a .028" tube or a .020" tube, the required reduction is

    .0028" or .0020". A small error in measurement can result in a large

    deficiency in pull-out strength.


    Why the titanium target price is high?


    Titanium target

    price is not cheap mainly due to the high price of its raw material titanium.

    Titanium sputtering target is mainly used for various film coatings, such as tool

    coating, optics coating, solar coating, and the like. However, its high price is a big

    obstacle for its popularity and development.


    We generally think gold & platinum are expensive because of their scarcity, but how

    about titanium? Is it a precious metal? Well, among the list of the top 10 most precious

    metals in the world, titanium, unfortunately, doesn’t get its place, which is a

    foregone conclusion. Titanium is present in the Earth’s crust at a level of about 0.6%

    — the fourth most abundant structural metal after aluminum, iron, and magnesium.


    However, titanium is always bonded to other elements in nature. Since titanium

    extraction is complex and costly, the price of the titanium product is high.


    What is titanium flange?


    Titanium flange

    is a kind of part made of non-ferrous metal titanium or titanium alloy to connect

    the pipe with the pipe, which is connected to the pipe end. There are holes on the

    titanium flange, and bolts make the two flanges tightly connected. The flange is sealed

    with gasket. Flange pipe fittings refer to the pipe fittings with flange (flange or

    adapter).

    It can be formed by threaded connection or welding. The flange connection is

    composed of a pair of flanges, a gasket and several bolts and nuts. The gasket is placed

    between the two flange sealing surfaces. After the nut is tightened, the specific

    pressure on the gasket surface reaches a certain value, and the deformation occurs, and

    the uneven parts on the sealing surface are filled, so that the connection is tight.


    According to the structure type, there are titanium lap Joint flange, titanium weld

    neck flange, titanium threaded flange and titanium blind flange, etc.

    Progress for the Titanium Industry


    Positive progress has been made towards the cost-effective application of titanium

    in vehicles for the mass market. The leading applications are cold wound springs

    manufactured from low-cost beta alloy, and exhaust systems manufactured from

    commercially pure titanium.


    These two classes of components are currently being manufactured for the automotive

    industry in titanium, using processes and tooling designed for manufacturing parts in

    steel.


    Automotive suppliers and manufacturers look at the total system cost, and while the

    titanium industry aims to develop low-cost alloys, it is clear that cheaper titanium

    alone will not guarantee an automotive application, but a competitively priced titanium

    component will.


    Therefore, there is a need to establish low-cost manufacturing methods for

    titanium parts. In working with

    automotive designers, the industry monitors the cost-benefit of using titanium, and

    remains abreast of all design and production developments, to reduce the cost and

    manufacturing challenges.


    Requirements of the Automotive Industry


    For automotive producers, style and performance remain key sales factors, but

    environmentally aware customers with increasingly educated social consciences want not

    only these, but also greater safety, minimum noise, maximum fuel economy, and the

    continued reduction of harmful emissions.


    The pressure of legislation, typically the US Corporate Average Fuel Efficiency

    (CAFE), adds to market competition and growing customer demand - forcing design and

    material changes. As demand increases for more fuel-efficient and environmentally

    friendly cars, affordability is less of an issue. More improvements are being

    incorporated into engines, suspension, and bodywork.


    Increases in the cost of fuel serve to hasten this process, which also allows for

    more to be spent on corrosion resistance, weight, and fuel-saving.

    What are Standard Parts


    When we say “Standard Parts” we mean machine elements or machine components. Our

    Standard parts are

    used as the building blocks for machines and products

    in many different industries.


    We say Standard because all our parts are standardized to common sizes in both inch

    and metric. We standardize our parts, so the engineers don’t have to customize each

    knob or handle for every project. Using standard parts makes it convenient and fast for

    design engineers to find parts by offering multiple different types and sizes. JW Winco

    also offers free CAD models for all of our parts to speed up the design process.

    What are Non-standard Parts


    The non-standard parts of the mould are generally the specification and shape, and

    the non-standard

    parts
    are called non-standard parts.In general, the non-standard parts of the

    mould are the drawings and requirements provided by the supplier for processing.And

    mould parts for the high precision and high quality requirements on hardware

    accessories, all the mould parts of the industrial and technical equipment requirements

    is very high, non-standard precision mold precision up to 0.001 MM tolerance.Such as:

    rubber injection mold and product contact parts in general are standard parts, before

    having the main mold, mold, after insert. Can also be said that in addition to the

    screw, water nozzle, plunger, aprons, spring, and the rest of the mold are almost

    standard parts.


    Tungstun

    magine a lump of iron the size of a tennis ball. Weigh it in your hand. Now

    let it drop on to your foot. How does that feel? Now imagine an identical object three

    times as dense. How would that feel if you dropped it? Would you ever walk again?

    That metal is Tungstun.

    As well as being incredibly dense it is also incredibly hard and has the

    highest melting point of all the elements at 3,422C.

    A century or so ago the world had no use for it - it was almost impossible

    to shape or work the stuff. Yet now we use tungsten to write with, to traverse glaciers,

    to emit X-rays and to destroy buildings without the use of explosives.

    To understand how this happened, we need to understand the competitive

    forces that have shaped everything in our world, and where better to start than a

    mystery at the heart of the evolution of life?

    For the first four billion years, life didn't actually do much evolving.

    Organisms were small, simple and fairly rare. Then around 500 million years ago

    something extraordinary happened - the fossil records show there was an incredible

    explosion of life.

    What is molybdenum and what does it do?


    Molydenum

    is a mineral that you need to stay healthy. Your body uses molybdenum to process

    proteins and genetic material like DNA. Molybdenum also helps break down drugs and toxic

    substances that enter the body.


    Niobium


    Niobium is used in alloys including stainless steel. It improves the strength of the

    alloys, particularly at low temperatures. Alloys containing niobium are used in jet

    engines and rockets, beams and girders for buildings and oil rigs, and oil and gas

    pipelines.


    This element also has superconducting properties. It is used in superconducting

    magnets for particle accelerators, MRI scanners and NMR equipment.


    Niobium oxide compounds are added to glass to increase the refractive index, which

    allows corrective glasses to be made with thinner lenses.
