Cemented carbide sheet production technology and processing precautions-2

       Application of hard alloy sheet



Tungsten steel sheet has excellent hardness, high hardness, good wear resistance, high elastic modulus, high compressive strength, good chemical stability (acid, alkali, high temperature oxidation), low impact toughness, low expansion coefficient, The characteristics of heat conduction and electrical conduction similar to those of iron and its alloys, due to the great advantages of tungsten steel turning tools, have been quickly promoted in industry. In just 50 years, due to the use of tungsten steel turning tools, the metal cutting speed has increased 200 times, from 10 meters per minute to more than two kilometers. Heat-resistant tungsten steel still maintains good elasticity and mechanical strength, and is generally used for thicker cutting, intermittent cutting and poor parts clamping. After coating, the effect is better, and it can be processed to various materials of HRC50°. Corresponding to general tungsten steel, it has 1 to 2 times the service life and excellent impact resistance.

Application range of cemented carbide sheet



The applications of cemented carbide plates are mainly divided into three categories:



1. Used to make blanking dies. It should be used to make high-speed die and multi-station progressive die for punching copper, aluminum, stainless steel, cold-rolled plate, EI sheet, Q195, SPCC, silicon steel sheet, hardware, standard parts, upper and lower punches and other thin sheets.



2. Used to make wear-resistant tools. Such as knives for woodworking industry, plastic crushing knives, etc.



3. Used to make high temperature resistant parts, wear resistant parts, and anti-shielding parts. Such as the guide rail of the machine tool, the anti-theft reinforcement plate of the ATM, etc.



4. Used to make corrosion-resistant parts in the chemical industry.



5. Anti-radiation and anti-corrosion materials for medical equipment.



6. The material properties of cemented carbide plates for different purposes are not consistent. When using, you should choose a suitable cemented carbide plate according to the application.
