Powder Metallurgical Moulds

Introduction:

Widely used in Powder Metallurgical  production because of their good strength,toughness and wear resistance.

Cemented carbide has a performance between the tools and construction materials between ceramics and high-speed steel, has a overall performance of high hardness, high strength, high density, corrosion resistance, high temperature oxidation resistance and low coefficient of expansion. Its life expectancy is ten times or even several times over steel. Commonly used cemented carbide die is cold heading die, drawing die, hexagonal die, spiral mold, etc., Cemented carbide die is very widely used in the mold industry. And the industry generally uses cemented carbide cobalt.

WC-Co cemented Tungsten carbide is a new high-performance engineering materials. The direct use of the finished product after sintering alloy is widely used in molds, tools, measuring tools and wear-resistant, corrosion-resistant parts and other fields. The study found, WC- Co alloy can be heat strengthened, reinforced composite handle life of f cemented carbide die is four times without heat treatment, is 50 times of the original the steel mold, technology, has a significant economic benefit.
