Bronze Foil CW452K 150 mm x 5 Meter

Bronze Foil - Bronze Sheet

Bronze is an alloy of copper (Cu) and tin (Sn). A distinction is made between wrought and cast alloys depending on the processing.

Typical application examples are connectors, contact pins, as well as general stamped and bent parts and springs, where good electrical conductivity is necessary

In contrast to brass, bronze can also be used in vacuum technology.

Properties material CW452K - 2.1020

The bronze alloy CW452K - also called two-alloy - is the most frequently used type of bronze with a tin content of approx. 6%.

The alloy CW452K is characterized by a particularly favorable combination of cold formability, strength and hardness.

In addition, bronze is very corrosion and wear-resistant as well as seawater-resistant and has good tinnability.

Technical information

Bronze cannot be magnetized and therefore cannot be clamped on grinding machines. Bronze plates can be laser cut well and are very easy to etch.

CuSn6 is easy to weld with all processes. However, the heat input at the weld seam can lead to a structural change that reduces the strength. Bronze is very suitable for soft soldering.

The high strength of the bronze plates or the material is achieved by cold forming during rolling. Therefore, the direction of rolling has a great influence on bending.

Other applications / properties:

• good corrosion resistance
• easy to solder
• easy to polish
• good cold formability
• good spring properties
• Use: springs of all kinds, metal hoses, etc.
• Application: paper, pulp, textile and chemical industry as well as in ship, machine and apparatus construction, tombstones
