　　Bronze alloy bushings (copper bushings for short) have been widely used in many mechanical equipment and engineering structures due to their excellent wear

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.
