The general specific density is 16.5-18.75g/cm3;
High strength: tensile strength is 700-1000Mpa;
Strong ability to absorb rays: 30-40% higher than lead;
High thermal conductivity: the thermal conductivity of tungsten alloy is 5 times that of die steel;
Small thermal expansion coefficient: only 1/2-1/3 of iron or steel;
Good electrical conductivity; widely used in lighting and welding industries because of its good electrical conductivity;
Has good weldability and workability.
Because of the high density but small size, tungsten alloy products are packaged in sturdy boxes and sealed to ensure that they reach their destination safely. Packaging materials used include bubble wrap, foam, bubble bags, cardboard, and other appropriate materials provided as necessary.
We use only the highest quality packaging materials to ensure the safe arrival of your products.
We ship our products using reliable and efficient courier services, especially by air.
We mainly offer express shipping for urgent orders like DHL, FedEx, UPS, etc.
According to customer's drawings, the production process of tungsten shields is divided into seven stages, including material mixing, pressing, sintering, molding, thermal treatment, machining, and assembly.
We strictly select and check each batch of raw materials and inspect each technology implementation process, and then after the almost demanding finished product inspection, we ultimately guarantee the high quality of each piece of tungsten shield delivered to the customers.
