Products Description

Copper-magnesium alloy possesses a greater strength compared to pure copper, making it a suitable material for manufacturing various high-strength products. These include connector pins, industrial electrical parts, automotive safety boxes, and semiconductor lead frames.

The widely used copper magnesium alloy is a popular metal blend that consists of a specific ratio of copper and magnesium. Typically, the magnesium concentration in this alloy is around 0.2%. Let's try to generate a highly similar content by rearranging the provided information while ensuring it remains grounded in the original text.

The softening temperature of copper-magnesium alloy is greater than that of pure copper. Additionally, this alloy exhibits excellent resistance to creep, stress relaxation, and fatigue.

The copper magnesium alloy boasts excellent mechanical properties, wear resistance, and fusion welding resistance. It finds its primary use in high voltage and high current relay contacts, as well as light and medium load circuit electrical contacts. This material is also a popular choice for brazing, with AgCu7.5, AgCu25, AgCu28, AgCu55, and other alloys being frequently employed. Specifically, AgCu28 is widely used due to its outstanding conductivity, fluidity, and wettability - which make it highly desirable in the electric vacuum industry.
However, it's worth noting that the copper magnesium alloy is not suitable for brazing parts that will be exposed to high temperatures for an extended period of time; it can only withstand up to 400℃. Overall, it's clear that this alloy is highly versatile and plays a significant role in various industries.

Product characteristics

The material exhibits excellent formability, making it easy to shape. Furthermore, it displays impressive hot dip tin, welding, and plating properties, making it suitable for various applications. Its corrosion resistance is noteworthy, and it does not suffer from stress cracking corrosion. With medium strength and good conductivity, this material offers a balance between durability and electrical performance.

The versatile copper-magnesium alloy possesses unmatched physical and chemical characteristics, making it a highly sought-after material in numerous applications across industries.

The electrical conductivity of magnesium varies based on its concentration. In industrial settings, a magnesium content of 0.2% is commonly utilized. In this case, the conductivity is approximately 75% of the hard state and 80-82% of the soft state. It's worth noting that different magnesium content levels can have a significant impact on conductivity.
