Product Details

Tungsten steel round bar is a kind of high hardness and high strength alloy material made of hard alloy tungsten steel (WC) as the main raw material, plus other precious metals and pasting phase by powder metallurgy.

Widely used in the production and processing fields: such as: micro drill bits in the PCB industry, electrode rods in the optoelectronic communication industry, tungsten steel drill bits in the machining industry, drill shanks, tungsten steel tips, push rods, wear-resistant precision parts, integral CNC milling cutters and Material selected for machining with a hole.

High strength and high hardness, excellent hardness, good wear resistance, high elastic modulus, high bending strength, good chemical stability (acid, alkali, high temperature oxidation), good impact toughness and low expansion coefficient , thermal conductivity, electrical conductivity and iron and its alloys are similar. Unique new process: vacuum high temperature and high pressure sintering. The product is pressure sintered in the final stage, which greatly reduces the porosity, improves the compactness, and greatly improves the mechanical properties of the product. Features: There are many material grades, which can be applied to different needs of use. The specifications are complete and the blank size is accurate (reducing the processing volume and improving the production efficiency).

Process flow: milling→recipe according to the application requirements→wet grinding→mixing→grinding→drying→sieving→post-forming agent→re-drying→sintering to make mixture→granulation→pressing→forming→low-pressure sintering→ Forming (blank) → flaw detection → cylindrical grinding (the blank does not have this process) → detection
