Powder metallurgy process in the automotive field, consumer electronics, machinery and equipment, communications, hardware and tools, and even the aviation field have powder metallurgy process applications, which also shows the wide range of powder metallurgy process and the importance of the process in the industry, the next Harber Metal will give you an introduction to the types of powder metallurgy parts and application areas:
Types of powder metallurgy parts
1: Structural parts
Copper, iron, copper alloy, aluminum alloy and other manufactured gears and a variety of force parts.
Sintered metal oil-bearing. Iron-based and copper-based porous bearings with a porosity of 15% to 25%, with voids filled with lubricant.
Copper backed sintered alloy bearings. The first layer is steel backed and the second layer is sintered copper-aluminum alloy.
DU, DX bearings, etc.
Structural parts applications: automobiles, machine tools, agricultural machinery, textile machinery, instruments, sewing machines, power tools, etc., internal combustion engines, railroad vehicles, metallurgical machinery, tape recorders, video recorders, micro-motors and so on.
Powder metallurgy gear
2: Friction parts
Clutch plates or brake bands made of steel backing and iron-based or copper-based powder compositions, etc.
Friction parts applications: friction components on automobiles, airplanes, tanks, construction machinery, machine tools and power machines.
3: Filter elements and other porous materials
Filter elements. Made of spherical bronze, nickel, iron, stainless steel, and other metal powders, with uniformly distributed pores in the form of cups, cones, cylinders and rods.
Hardened and cooled materials. Rods, strips, and cylindrical products having up to 50% porosity manufactured from nickel, nickel-chromium alloys, stainless steel, and other corrosion-resistant materials.
Fiber metal products. Products with high porosity (up to 80%) manufactured from fine metal fibers.
Filter elements and other porous material applications: chemical industry, machine tools, aircraft, automobiles, internal combustion engines, etc., used to filter various gases and liquids, used as a jet element in the porous metal filter, aircraft for porous quenching and cooling elements, acoustic panels, special-purpose filtration of the original.
Powder metallurgy products are used in a wide range of applications, from general machinery manufacturing to precision instruments; from hardware tools to large-scale machinery; from the electronics industry to the motor manufacturing; from the civil industry to the military industry; from the general technology to the cutting-edge high-tech, powder metallurgy process is invisible.
Powder Metallurgy Products
Typical Applications–Automotive Industry
A large number of powder metallurgy parts are used in automobiles, such as:
1、Engine parts
In order to improve fuel economy and control emissions, the working conditions of automobile engines have become more severe. The use of powder metallurgy valve seats, valve guides, VCTs and sprockets can have high strength, high wear resistance and excellent heat resistance.
2、Drive components
The world’s first clutch hub was made by combining an almost molded synchromesh ring with double friction materials and high-strength materials. In addition, high strength parts such as handle shift gears and shift forks are manufactured through high temperature sintering.
Powder metallurgy transmission parts in automobiles mainly include: synchronizer hubs, synchronizer rings, parking parts, shift column parts and joysticks.
3、Shock absorber components
In the shock absorbers of automobiles and motorcycles, piston rods and piston guide valves are important components. Considering the stable damping force of shock absorbers, the use of powder metallurgy parts with high-precision sheet surfaces reduces friction, ensures handling stability and enhances ride comfort.
Typical Applications – Aerospace Industry
Powder metallurgy materials for the aerospace industry, one category is special functional materials, such as friction materials, friction reduction materials, sealing materials, filtration materials, etc., which are mainly used for aircraft and engine auxiliaries, instruments and on-board equipment. Another category is high-temperature and high-strength structural materials, which are mainly used for important structural parts of aircraft engine hosts.
Typical applications – household appliances
Some materials and parts of household appliances can only be manufactured by powder metallurgy, such as refrigerators, compressors, washing machines, electric fans in the porous self-lubricating bearings and so on. Some materials and parts for household appliances can be manufactured by powder metallurgy with better quality and lower price, for example, complex shapes of gears and magnets in household air-conditioner exhaust fans and vacuum cleaners.
