Determination of cobalt magnetism of cemented alloys
Tungsten carbide cobalt magnetism, also known as the saturation magnetization strength of the alloy, is actually the saturation magnetization strength of the magnetic material cobalt. The cobalt magnetism of tungsten carbide is also based on the ratio of its magnetic material cobalt content to th...Read more -
Tungsten carbide coercivity magnetism
Tungsten carbide coercive magnetism is the magnitude of the reverse magnetic strength required to completely demagnetize a magnetic material. The coercivity magnetism of carbide decreases with increasing cobalt content and increases with finer grain size. The coercivity magnetism is measured to e...Read more -

Effect of vacuum sintering process on tungsten carbide moulds
The role of vacuum sintering of tungsten carbide mold mainly has the following aspects: 1. Improve hardness and toughness: Vacuum sintering is a method of sintering tungsten carbide powder into cemented carbide by using high temperature and high pressure. Through vacuum sintering, tungsten carbi...Read more -
What is Cold Heading
Cold heading is a metalworking process whereby a metal bar or wire is transformed from a larger diameter round bar or wire to a smaller diameter steel wire or rebar by applying a strong force to it in a die at room temperature, while also changing the shape of the metal cross-section. The process...Read more -
Improve management level and move forward to high quality development.
High-quality construction to create high-quality tungsten carbide products is not easy, shouting slogans can be achieved. Orders are the same, which have so many batch, non-standard shaped mostly, which requires more brains, deeper research, lack of development, research and development, a look a...Read more -
No stopping forward, no stopping the struggle.
This afternoon in the Research Department General Manager Liu listened to a report on the sintering mode attended by the Director of the Research Department and the Production Management Department. It was decided that: First, the number of people in the tungsten carbide sintering workshop is re...Read more -
How long is the service life of cold heading die
The service life of cold heading dies depends on many factors, including materials used, processed materials, equipment temperature, surface treatment and so on. Generally speaking, the life of cold heading dies can reach millions or tens of millions of impacts. In order to ensure the life of co...Read more -
Ways to extend the life of tungsten carbide cold heading dies
To prolong the life of cold heading dies, we can mainly start from the following aspects: 1. Reasonable selection of mold materials: The material of cold heading molds should be selected according to the type of steel produced, hardness, cross-sectional shape and working environment and other fac...Read more -
