Product Detail
Why choose Tungsten as the material for Cannon Ball and slingshot ammo? Here are the reasons.
A) Density:
Hunters are well acquainted with the advantage of lead, 11.3 gr/cm3 density over steel 7.8 gr/cm3,with a 45% greater density, it's significantly smaller for the same mass, which translates into greater penetrating power and less aerodynamic drag. And tungsten has roughly the same mass advantage much over steel: at 14-18.5 gr/ccm density.
B} Hardness:
Tungsten Carbide is TOUGH stuff. It can be chosen as munition in anti-personnel fragmentation munitions.
C) Non-Toxicity:
Unlike lead, which is a toxic heavy metal, carbide is relatively non-toxic.
D) Corrosion Resistance:
Carbide is naturally stable because the tungsten is already in a highly stable molecular bond with carbon, and is therefore resistant to corrosion in most ambient temperature conditions.
E) High Melting Point:
Tungsten has a very high melting point you find it was/is the chief ingredient in the filaments used in incandescent light bulbs.
MIM PROCESSES
The CORE TECHNOLOGIES KELU has are MIM and CNC, both for the high-end sport components.
Metal injection molding (MIM) is a revolutionary technology which integrating Plastic Injection Molding, Polymer chemistry, Powder metallurgy and Metallic materials science. We can develop mold for special customized size/shape or produce by existing mold directly. Tungsten, Brass, Stainless Steel could be chosen as materials for MIM.
Computer numerical control (CNC) is the automation of machine tools by means of computers executing pre-programmed sequences of machine control commands. And its applicative materials include Titanium, Tungsten, Aluminum, Brass, Stainless Steel, Zinc and so on.
KELU's Main Markets：
North American, Europe, Australia, Asia
