Copper casting and bronze casting are resistant to corrosion and chemicals

Copper castings are resistant to corrosion and chemicals. Maintenance-free, long service life, widely used in automotive molds and plastic molds. Self-lubricating copper sleeves, sliders, guides, guide sleeves, etc. are widely used in automotive stamping dies (drop blanks, drawing dies, bending dies, punching trimming dies, edging dies, etc.) and mechanical equipment (plastic machinery, Construction machinery, metallurgical forging, mining machinery, etc.Bronze casting manufacturers is about to say.

There are many classification methods for copper castings: according to the metal materials used, they are divided into steel castings, cast iron parts, cast copper parts, cast aluminum parts, and copper castings. Each type of casting can be further divided into different varieties according to its chemical composition or metallographic structure. For example, cast iron parts can be divided into gray cast iron parts, malleable cast iron parts, alloy cast iron parts, etc.; according to the different molding methods, the castings can be divided into ordinary sand castings, metal castings, die castings, ceramic castings, electroslag remelting castings. Parts, bimetal castings, etc. Among them, ordinary sand castings are the most widely used, accounting for about 80% of all castings. Non-ferrous metal castings such as aluminum, magnesium and zinc are mostly die-casting parts.

The birth of the ancient Chinese bronze casting industry has created a civilization of the Bronze Age. Bronze is one of the carriers of the splendid civilization in ancient China. It is famous for its wide variety of styles, exquisite shapes, rigorous and realistic paintings, and advanced and perfect casting technology. The bronze wares formed the style characteristics of each period in the development process. The bronze wares of the Shang and Zhou dynasties were famous for their quaint and simple simplicity. The bronze wares of the Spring and Autumn Period and the Warring States Period had the new characteristics of making dexterity and vivid decoration.
