Description
Alloy AO9−1 is applied: to obtain a bimetal strip with steel and aluminum by rolling and subsequent punching of liners with a thickness of friction layer is less than 1 mm.
Note
The recommended modes of operation:
— load ≤ 29,5 Mn/m2 (300 kgf/cm2);
— sliding speed ≤ 20 m/s;
temperature ≤ 120 °C;
— recommended shaft hardness ≥ 250 HB.
On an antifriction layer of articles coated with a soft metal or a polymer antifriction coating thickness of from 0.003 to 0.03 mm. permitted by agreement with the consumer in technically justified cases to cover the product with a soft metal or polymer coating.
