High specific gravity tungsten alloy material is a kind of alloy with tungsten as the matrix (W content 85-99%) and added with elements such as Ni, Cu, Co, Mo, Cr. According to alloy composition characteristics and uses, it can be divided into main series such as W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag, and its density is between 16.5-19.0g/cm3 Adjustable. Generally, large and special-shaped parts are produced by isostatic pressing technology, small products are produced by mould pressing, extrusion and injection moulding technology, and bars and sheets are produced and processed by forging and rolling.
Advantage:
Specific gravity: general specific gravity is 16.5-18.75g/cm3;
High strength: the tensile strength is 700-1000Mpa;
Strong ability to absorb rays: its ability is 30-40% higher than that of lead, and it is not harmful to the environment and health;
Large thermal conductivity: 5 times that of die steel;
Small thermal expansion coefficient: only 1/2-1/3 of iron or steel, good electrical conductivity;
It has good weldability and easy cutting.
Use:
Mainly used as aerospace gyro rotor, counterweight, shock absorption device, conventional weapon armor-piercing projectile core, radiation shielding device and components, die-casting molds for mechanical manufacturing, flywheels and automatic watch pendulums, etc., electrical equipment Counterweights such as contacts and electrodes.
