The contribution of powder metallurgy in the automotive industry

Powder metallurgy is a kind of mechanical structure parts manufacturing technology that can produce complex shape parts, save material and labor, and is very suitable for mass production. Therefore, in the United States and Japan, the development of powder metallurgy structure parts and automobile industry is synchronized. It is reported that there are over 1000 kinds of POWDER metallurgy parts used in automobiles.

Car horn in the radio mini TV VCR instruments used in the hard and soft magnetic magnetic components, automotive starter generator used in the brush, the platinum distributor contact contact (w), car tyres containing cleats, unleaded gasoline engine exhaust valve seat, sintered metal oil filter of diesel engine, heavy duty truck brake friction materials, automobile, widely used in DU DX bearing and bimetallic bearing shell and is widely used in automobile manufacture carbide cutting tools, measuring tool and die, etc., all of these products or materials can only be made of powder metallurgy technology.

Material due to its energy saving province efficient environmental protection, and many other advantages, has been widely used, and has great market potential and development prospects in recent years, powder metallurgy industry developing rapidly, especially in the auto industry machinery manufacturing metal industry aerospace instrumentation hardware engineering machinery electronic appliances and the rapid development of high-tech industries, for the powder metallurgy industry has brought rare opportunities for development and huge market space and technical level of the industry are also put forward higher requirements, and the basis of the production of powder metallurgical product raw material, is the reduced iron powderThe production of reduced iron powder is divided into two stages. Firstly, sponge iron is produced by the reduction of solid carbon in tunnel kiln, which is broken into powder, commonly known as primary reduction, followed by the so-called secondary reduction by the decomposition of ammonia or hydrogen in belt furnace.
