Bronze, an alloy of copper and other metals such as tin and aluminum, is a widely used metal material in the early history of mankind. Its unique properties mak

The important characteristics of bronze bushings mainly include the following points:

1‌. Strong corrosion resistance ‌: Bronze bushings have good corrosion resistance in atmospheric and freshwater environments, can resist the erosion of various chemical elements, and are not prone to seizure. ‌

Inspection requirements and precautions for bronze castings
Inspection requirements:

1.Surface quality inspection: 5B test, salt spray test, and UV resistance test are required to ensure that the surface quality of castings meets the standards.

2.Shape and size inspection: According to the use requirements, flatness, parallelism, straightness and other inspections are carried out to ensure that the shape and size of the castings meet the design requirements.

3.Internal quality inspection: Including chemical composition, mechanical properties, etc., to ensure that the internal quality of the castings meets the standards.

‌Mechanical property test of bronze bushing‌

‌Hardness test‌: The hardness of bronze bushing is a key indicator. The hardness of bronze with different alloy compositions varies. For example, the hardness of pure copper is 35 degrees (Boling hardness tester), while the hardness of tin bronze increases with the increase of tin content, ranging from 50 to 80 degrees‌.

The manufacturing accuracy of bronze bushing molds depends largely on the application requirements of the molds, the processing equipment used, and the processi

It is common knowledge that metals can corrode. Affected by the environment, destructive damage is caused by chemical or electrochemical reactions. It can be sa
