Product Description

AMS 7725 Tungsten Alloy Rod is an ideal choice for radiation shielding, ordnance parts and high temperature tools. Kefeng has excellent
processing capability. We can manufacture standard sizes or customized products according to your specific specifications. High-density tungsten alloy provides a unique combination of density, mechanical strength, work-ability, corrosion resistance and economy. Compared with traditional lead or uranium, it has superior advantages. 

Characteristics and features
Different sizes with high density, high melting point , high hardness, excellent wear resistance , high ultimate tensile strength , good extension , low vapor pressure , heat resistant, good thermal stability , easy processing, corrosion resistance, good shock resistance , high radiation absorption capacity , excellent impact resistance and crack resistance , and non-toxic environmental protection Is consistent with international environmental protection standards.









Application
For tungsten alloy rods with ASTM B777 are usually used to making the parts of counterweights for oil logging, artillery, rocket, satellite, aircraft, boats, radiation shielding, welding rod, aerospace components, mechanical manufacture parts,extrusion die, sports fields, such as darts, billets and golf club.

For tungsten alloy rods with AMS7725, it can be mainly used in:

1. Resistance welding electrode
2. Electric upsetting anvil
3. Radio shielding material, the collimator in the flaw detector and the clinical radio-shielding needle.
4. Partial balance weight
5. Other fields in aviation equipment and fishery equipment to replace uranium and lead without pollution.
