Copper castings are commonly used materials for making various mechanical equipment and parts. Due to their excellent conductivity and mechanical strength, they are widely used in fields such as automobiles, airplanes, power equipment, and home decoration.

1、 Types of copper castings

Copper castings can be divided into pure copper castings, brass castings, aluminum bronze castings, phosphor bronze castings, etc. according to different materials and production processes. Among them, pure copper castings have the advantages of high electrical conductivity, good corrosion resistance, and strong machinability, but the price is relatively high; Brass castings have the characteristics of high mechanical strength, good waterproof ability, and relatively low cost, and are often used in machinery and shipbuilding; Aluminum bronze castings have the advantages of light volume, high strength, and expanded application range, and are widely used in fields such as aerospace and electronic instruments.

2、 Methods for selecting copper castings

1. Check the materials, processes, and specifications before making a purchase. The quality and performance of copper castings are closely related to materials, processes, and specifications. Different varieties and specifications of copper castings should be selected for different purposes and occasions.

2. Observe surface quality and details. The surface of copper castings should be smooth, flawless, and free from obvious porosity or shrinkage. Additionally, it is important to pay attention to details such as the end face, mouth shape, and fillet radius to ensure proper fit and longevity.

3. Measure size and error. Proper use of measuring tools for size and error measurement, especially for precision mechanical components and high-tech equipment, requires even stricter requirements.

4. Master the price and after-sales service. Before purchasing copper castings, it is important to understand the relevant market conditions and product prices, as well as the after-sales service policy and warranty period.

3、 Maintenance techniques for copper castings

1. Avoid friction and collision. Copper castings are prone to scratches and damage, so they should be handled with care during use and storage to avoid friction and collision with other hard objects.

2. Regular cleaning and oiling. Copper castings may produce rust and stains during use, and should be regularly cleaned and coated with oil for rust prevention. At the same time, appropriate cleaning and oiling agents should be selected to avoid damage to copper castings.

3. Store in a dry and ventilated place. Copper castings generally need to be stored in a dry and ventilated place to avoid moisture and corrosion. Before storage, it should be dried and rust proofed to extend its service life.
