Composition of the material: Powder antifriction material on the base of iron and copper with additives of hard lubricant from molybdenum disulfide and fusible metals PA-GZGr₂D₂₀S₁₀ and PА-BrOGZMs.

Main characteristics of the material:

• Porosity - 18 - 25 %;
• Oil absorption – 1,8 % minimum;
• Destruction effort at radial pressure – 950 … 1 000 MPa minimum;
• Friction coefficient (at Р = 2,8 MPa, ? = 4 m/s) – 0,015 … 0,03;
• Gripping pressure – 4.2…4,5 MPa;
• Wear intensity (at Р = 2,8 MPa, ? = 4 m/s) – 34,7•10^-12 ?m/km

Type and characteristics of products: Inserts of starters of cars and trucks being made from this material are characterized by the complex of mechanical and tribotechnical properties and by better conditions of self-lubrication in comparison with bronze.

An output mastery of developed products: An output of the production is mastered at the Pilot Plant of the Powder Metallurgy Institute. Yield is 2,0 million pieces per year.

Scientific and technical level, novelty: The level of the best domestic and foreign analogues. The patent of Belarus № 1334.
