Purpose of the development: The new alloy which have improved wear resistance and low coefficient of linear expansion is used for manufacturing various parts ekspluatiruyuemyh at elevated temperatures. Application: - Details of the cylinders and pistons uprated engines; - The details of devices that need to be improved dimensional stability and shape.

Technical characteristic: Temperature, deg. S - 20, 150, 250 Density, kg/m3 - 2620 - - Hardness HB (can be changed on request) - 195-135, 145-115, 115-95 Tensile strength stretching, MPa - 320-280, 227-210, 175-155 Compressive strength, MPa - 410-380 -, 300-270 Coefficient of linear expansion, x10 (6) 1/Grade C - 12,1-11,5 -; 15,7-15,6

Advantages over analogues: The test engine parts ukoplektovanih alloy ALREZIST conducted on laboratory benches and in the field, have shown their advantages over conventional

The development stage readiness: Ready for application

Technical and economic effect: ALREZIST alloy is produced using new physical principles of structure, 15 Parts of it are made by compacting and extrusion. It uses a standard production equipment. Two physical-mehanіchnі and service properties of the alloy ALREZIST guarantee: - Stability of dimensions and shapes of parts of devices in a wide temperature range; - Lower half abrasion contact "compression ring - piston groove"; - Lighter weight machine parts, which reduces the load and improves the dynamic equilibrium of the engine; - Reducing the gap between the piston and the cylinder, which reduces the cost of oil, the level of noise and loss of power; - Reducing the thermal growth of the size of pistons 40 - 60% compared with the Al alloy of 12% Si.
