5N-7N Copper sheet

High purity copper 5N-7N copper sheet is a kind of metal copper sheet with a purity of 99.999% to 99.99999%. It is a kind of special supporting material for the preparation of high-purity target materials, mainly used in integrated circuits, large-size displays and other semiconductor fields, and is a key material to promote the development of microelectronics industry.

High purity copper 5N-7N copper sheet has the following characteristics:

• Excellent electrical conductivity, low resistivity, can be used to make high-performance cables, bonded wire, etc.
• Good corrosion resistance, not easy oxidation, can be used to make high temperature, acid and alkali resistant equipment and parts.
• The malleability and malleability are strong, and can be made into the required shape and size by various processing methods.
• High purity, low impurity content, can ensure the quality and stability of the product.
• The impurity elements such as Ag and S were continuously and stably controlled to ultra-low levels

Specification of high purity copper 5N-7N copper sheet:

• The length, width, thickness and weight of copper sheet can be customized according to customer requirements
• Purity: 5N (99.999%) or 6N (99.9999%) or 7N (99.99999%)
