WHA-Tungsten Pinewood Derby Car Slugs Weights
China WHA-Tungsten Pinewood Derby Car Slugs Weights, Find details about China Tungsten Weights, Pinewood Derby Car Weights from WHA-Tungsten Pinewood Derby Car Slugs Weights
Tungsten heavy alloys generally are refractory metal, which have two-phase
composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some
tungsten alloy is added Co, Mo, Cr, etc. It could be made as various shapes,
such as rod, cube, block, brick, ring, etc.
1. Dimension: according to customer's requirement.
2. Density: 15.8-18.50 g/cm3
3. Composition: W content: 85-97%, W-Ni-Fe, W-Ni-Cu
4. Surface: Sinter state, Grind state, processing state with chamfer angle
5. Application: balance weight, Military industry
Main Performance of the Tungsten Alloy
Tungsten alloy has many special properties, such as: small size with high
density, high melting point , high hardness , excellent wear resistance , high
ultimate tensile strength , extension of good , 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.
Appliance of Tungsten Heavy Alloy Slug
Usually, tungsten alloy cylinder could be manufactured as the parts of military
defense, for penetrating projectiles, counterweights for military defense,
projectiles in the missile weapons, armor piercing ammunition, and
prefabricated fragments.
Balance weight: such as Pinewood Derby car counterweight, yacht
counterweights, vehicle counterweights, airplane counterweights, helicopter
counterweights, boat counterweights, tank counterweights, crankshaft
counterweights etc.
