ALUMINIUM-BASE ANTIFRICTION ALLOY Russian patent published in 1995 - IPC

FIELD: alloys. SUBSTANCE: alloy has, wt.-%: tin 15-30; copper 6-16; magnesium 0.1-2.0; manganese 0.1-1.5, and aluminium - the rest. Alloy properties: hardness is 95.5-114 kgf/mm², strength limit is 209-216 MPa; flowability limit is 115-127 MPa; relative elongation is 4.0-4.5; wearing intensity for 1000 m friction way is (0.90-1.04) ·10^-4 mm³/cm²; friction coefficient at 0.52 m/s with lubricant is 0.001-0.012. Alloy is used for making of friction slipping units. EFFECT: enhanced quality of alloy. 3 tbl
