With the development of modern powder metallurgical manufacturing technology, we can see powder metallurgical technology in the electronics industry, motor manufacturing, civilian industry, and military industry. Powder metallurgical products have become an indispensable supporting basic parts in various industries. So, what are the main types of powder metallurgical materials?

1. Hard alloy:

Hard alloys are based on the powder of one or more pink molten carbonizes. The cobalt powder that is bonded is added to the material made of powder metallurgy. The commonly used hard alloys are divided into: tungsten cobalt, tungsten cobalt titanium, tungsten titanium (铌) class. High hardness, high hard hardness, good abrasion resistance, high pressure resistance, high bending strength and poor toughness. Corrosion resistance and good antioxidant. Line expansion coefficients are small, but poor thermal conductivity.

2. Fan Metallurgical Drimp Making Materials:

Different powder metallurgy is divided into iron -based materials and copper -based materials depending on the substrate main additional elements. Iron-based reduction materials are iron-graphite powder alloys and iron-sulfur-graphite powder alloys. The former is the tissue of pearl body+iron body+carburizing+graphite+pores; in addition to the same tissue as the former tissue, the latter can further improve the reduction. Powder metallurgical reduction materials are generally used for manufacturing bearing of medium speed and light load. It is especially suitable for bearing that cannot be refuated, such as textile machinery, film machinery, food machinery, household appliances, etc. There are also applications.

3. Powder metallurgical structure materials:

Powder metallurgical structure materials are divided into iron and copper -based materials depending on the substrate metal. Compared with iron -based structure materials, copper -based structural materials are low -tensile strength, high plasticity and toughness, and have good conductivity, heat conduction and corrosion resistance. Various plating treatment can be performed. , High -size accuracy and small stress instrumental parts and electrical appliances, mechanical product parts, such as small molds, cams, fasteners, valves, sales, sets and other structural parts.

4. Powder metallurgical friction materials:

Powder metallurgy friction materials are divided into iron and copper -based materials according to different matrix metals. According to different working conditions, they are divided into dry and wet materials. Wet materials are suitable for working in oil. Powder metallurgy friction materials are mainly used to make machine tools, tractors, cars, mining vehicles, construction machinery and clutch and brakes on aircraft.

The above is the main type of powder metallurgical materials. Powder metallurgical products can be divided into powder metallurgical mechanical parts, friction materials, magnetic materials, hard alloy materials, etc. Wide in the field, large demand, and high technical content, is a leading product in the powder metallurgical industry.
