## Abstract

The invention relates to a plain bearing alloy on a tin basis with antimony and copper, the alloy consisting of 6 to 15% by weight of antimony, 3 to 10% by weight of copper, 0.05 to 1% by weight of silver and 0.1 to 2% by weight of zinc, the remainder being tin.

## Claims

### Claim 1

A plain bearing alloy based on tin, antimony and copper, comprising of 6 to 15% by weight of antimony, 3 to 10% by weight of copper, 0.05 to 1% by weight of silver and 0.1 to 2% by weight of zinc, the remainder being tin.

### Claim 2 (depends on 1)

The plain bearing alloy of claim 1, wherein the silver content is 0.05 to 0.15% by weight.

### Claim 3 (depends on 2)

The plain bearing alloy of claim 2, wherein the silver content is 0.1% by weight.

### Claim 4 (depends on 1, 2, 3)

The plain bearing alloy of claims 1, 2 or 3, wherein the zinc content is 0.5 to 0.7% by weight.

### Claim 5 (depends on 1, 2, 3)

The plain bearing alloy of claims 1, 2 or 3, wherein the zinc content is 0.6% by weight.
