Tungsten Heavy Alloy Rod(HM Rod)
Tungsten heavy alloy rod refers to high density tungsten-base alloy rod with nickel and iron matrix, it typically divided to civil use and military use.the tungsten alloy rod basically have four class accordingly :Class1 90W;Class2 93W;Class3 95W;Class4 97W.different demand require different tungsten rod,such as forged rod, ground rod , sintering rod or even fine precision rod. We usually produce swage rod benchmark Class2 as military source. Regarding high performance swage rod need further processing so as to its properties escalate .details about high performance swage rod welcome consult us.
These kinds of tungsten alloy rod can be machined further into the parts of counterweights,ion implantation parts , electric light source parts and electric vacuum components,heating elements,refractory parts in high temperature furnaces, radiation shielding, military defense appliances, welding rods, extrusion dies or radiation shielding. some are used in sports to create darts, billets, golf club.
