Tungsten alloy is an environmentally friendly, durable and a hardness material, the most important is its density, close to the density of gold (19.3g/cm3). These advantages of the tungsten alloy makes tungsten alloy gold-plated bullion products enjoy certain advantages,tungsten alloy golden bullion,gold-plated bullion is the best alternative of the expensive metal gold or platinum.
Gold plated tungsten ring is remarkably durable and incredibly scratch resistant. Tungsten is about 10 times harder than 18K gold, 5 times harder than tool steel, and 4 times harder than titanium. Gold plated tungsten ring is the most wear resistant rings available on the planet. Tungsten ring has been referred to as the "Permanently Polished Ring".
As its high density, high melting point, small capacity, excellent hardness, superior wearing resistance, high ultimate tensile strength, high-density, good machinability, good mechanical properties, high modulus properties, harmless to the health and environment etc, tungsten alloy rod is increasingly welcomed by public.
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.
