Bronze alloy CuSn5ZnPb5

Identification: CuSn5Zn5Pb5

Grade: casting tin bronze. It has duplex structure. It is alloyed with phosphorus, plumb, zinc.

Industrial usage: bearing bushes, antifriction details, fitting.

Percentage composition according to GOST 613−79

Element Content
P <0,1
Cu 80.7 — 88
Si <0,05
Fe <0,4
Sb <0,5
Zn 4 — 6
Pb 4 — 6
Sn 4 — 6

Alloying components increase density, fluidity of material and significantly reduce tendency to segregation. Bronze of this grade is badly exposed to pressure treatment. However, it possesses good resistance to corrosion, excellent cutability. This bronze has excellent antifriction properties. It is used in a manufacture of sleeve bearing blocks. Shims, bushings for tractors and cars are made of this grade.

Main properties:

Coefficient of friction with lubricant = 0.016

Coefficient of friction without lubricant = 0.26

Alloy hardness = HB 10 -1 = 60 MPа

Heat treatment: without heat treatment

Linear shrinkage = 1.5%

Casting temperature = 1250 — 1300°C

This grade is one of the most requested bronzes on contemporary market of bronze mill-products. Bushings, pipe products, rod are manufactured with a help of continuous casting. In comparison with a pressing method, casting of bar assumes high strength, perfect physical properties. Such alloy has a vast scope of application. Cracks, surface blemishes, over prominence must not be present on a metal surface. However, there are acceptable markings made by withdrawal-roll facility. Bushing is made with a help of centrifugal casting and further machine processing. Bushing has high strength even at increased loads and rough working conditions. Pipes made of this alloy are very popular because they are resistant to corrosion.
