Tungsten heavy metal foil and tungsten strip is extremely heat-proof and heat-resistant.

It has small thermal expansion coefficient, high resistance to thermal creep, good thermal conductivity and high electron emission coefficient. Tungsten heavy metal foil is very solid; it has very high tensile modulus and compression.

It is resistant to corrosion, the action of alkalis and acids, including concentrated hydrochloric, sulfuric and nitric acids, aqua regia, which makes tungsten foil suitable in various fields use.

Tungsten carbide ball is typical of brittle products. Traditional tungsten carbide ball is made of a traditional uniform carbide (convention a homogeneous cemented carbide, CHCC) material, a uniform composition and organization of its parts, the entire alloy is homogeneous, with the consistency of its performance. The main component of the cemented carbide comprising a hard phase and a variety of binder phase, the hard phase (e.g. WC phase, solid solution phase) from the hardness and wear resistance of tungsten carbide ball important role, relative tungsten carbide ball bonding have an important impact toughness.

In general, increasing the WC grain size or increase of Co content, can increase the thickness of the binder phase of cemented carbide, cemented carbide can be improved ductility. Carbide good plasticity, deformation may be due to local stress concentration and relaxation; plasticity carbide poor, due to stress relaxation caused by crack initiation and propagation, resulting alloy fragmentation. Therefore, the traditional approach is to improve the content of Co cemented carbide and WC grain size increases as the direction of improving the toughness of tungsten carbide ball. But this makes the hardness and wear resistance while also declined; on the contrary, the hardness and wear resistance can be improved, but at the expense of flexural strength and impact toughness. Therefore, between the tungsten carbide ball material hardness and toughness sharp contradiction exists.
