Product Description

Our 4047 and 4032 extra flat aluminum sheets/coils for laser welding for Electronic Components.

These two alloys are suitable for laser welding and brazing, compared with other alloys.
4047 alloy is with high content of silicon which gives low melting point, 4032 is with high content of Si meanwhile the strength of the sheet is high.
Under our sound management of cutting,we offer the aluminum sheet or coil with great surface condition and flatness which ensures the high yield at our clients end.

Products' advantages:
1) Low melting point, suitable for laser welding and brazing.2) Low thermal expansivity, suitable for combine with other metals.
3) Good control of the cutting burr, scratch and flatness.
