Use high density materials to produce High Explosive-Anti-Tank cover, such as tungsten alloy counterweight, to enhance piercing projectile power, then replace the traditional copper shaped charge liner materials.In order to meet the needs of future war, and is being studied in many countries of the world.United States, Ken Fok company,comparison with copper hood,tungsten-copper-nickel armor-penetration depth of liner more than 31%,comparison with copper hood.Germany, and France's researchers had also confirmed this, with tungsten alloy formed by tungsten shaped charge liner with two characteristics of the shaped charge liner with high performance.High density and high elongation of the Jet before breaking led its extension.
Tungsten-copper-nickel alloy liner shaped charge on homogeneous armor penetration will increase 38%, forming the Jets better than the tensile properties of the copper Jet, but it must be noted that tungsten-copper-nickel alloy liner is not the density, the higher the better the armor, it is important to ensure materials have good uniformity.Uniform density distributions of a single CAP, no defects, experiments show that material with tungsten-copper-nickel alloy liner to enhance penetration power is very effective and feasible.

Tungsten heavy alloy(WHA) balance weight of racing car is now becoming the most popular material for ballast, due to its main advantages as follows:
Highest density: Adding WHA balance weight into the whole framework of aracing car is helpful to optimize the performance of the racing car during the racing progress, which contributes to the better control of the car’s movement.
High tensile strength and good creep resistance: Tungsten has high tensile strength and good creep resistance with a high mass/size ratio, so it will be the ideal to work in are strict space. Its high density also gives enhanced sensitivity by increasing the control of load distribution.
Machined Easily: WHA is also easily machineable which gives designers greater flexibility in deciding on the final shape of components and offer designers several advantages over conventional balance materials e.g. lead or steel.

The insert has a cemented metal carbide core containing a majority of tungsten carbide and possibly other metal carbides bonded with an iron group metal, e.g. cobalt, nickel or iron providing a tough, deformation resistant material which can withstand the stresses of machining.
The core material has a thin layer of crater-resistant cemented carbide disposed on the rake face thereof, said crater-resistant layer containing tungsten carbide and substantial amounts of a carbide of a metal chosen from Groups IVb and Vb of the periodic table, the percentage of the Group IVb and Vb carbides is greater in the crater-resistant layer than in the core material. A thin coating of hard surface material coated on the composite substrate's rake face and flanks provides a coated, laminated structure which is resistant to cratering, flank wear and deformation even under high speed machining conditions.

Drivers consistently report they can sense differences in how a car handles on the track if the weight on a given wheel varies only by a couple of pounds. Fine tuning a car to a given track is a very cumbersome and time consuming ordeal with conventional lead plate weights.
WHA weight blocks offer up to 50% more weight in a given volume, with the added advantages of direct attachment via threaded holes orthru-bolting and the freedom from deformation. The high density of WHAs permit weights to be placed in the lower half of NASCAR weight adjustment tubes,effectively lowering the overall center of gravity for improved handling.Tungsten product has a specialized line of racing weights for these applications.

Pure titanium carbide tool has excellent crater resistance but only limited strength; however, the laminated composite substrate under the titanium carbide coating supports and supplements the titanium carbide coating extending the useful life of the insert even after the titanium carbide coating has been abraded away.
It is also thought that the TiC coating reduces machining temperatures because of its low frictional coefficient even though it is a very thin coating and provides protection from heat buildup in the laminated composite substrate during cutting operations. A further hard surface coating is aluminum oxide which when coated over the composite substrate produces an insert combining the toughness of the carbide with the wear resistance and low reactivity of aluminum oxide.
