Nickel strip belt pure nickel strip for Li 21700 batteries spot welding nickel strip tap 0.15x32x23.4mm (0.2mm thickness)

high purity pure nickel strip，Purity reached 99.96%nickel strip comes 0.15mm thickness x 32mm wide x 23.4mm width of inner hole size 2P suit for 18650 batteries spot weldingWill not rust, easy to weld for batteries,5Metes/roll, Suitable for small battery projects, one whole, One continuous piece, no cut and no waste,High purity nickel, never corroded and looseHow to determine whether it is pure nickel?1, nickel belt usually has pure nickel belt and nickel-plated steel belt, pure nickel belt is relatively soft, and nickel-plated steel belt is relatively hard, in addition, because nickel density is larger than steel, in the same size and weight, they The volume is different,2, using a grinding machine to polish, sparks, not pure nickel belt, pure nickel belt will not have sparks, this is the most simple and effective way,3, the nickel element is a magnetic metal, with weak magnetic properties, can be attracted by the magnet, Please correct a misunderstanding that being attracted to a magnet is not pure nickel.4, pure nickel belt will never rust, corrosion, can be soaked with salt water, testing

• Nickel strip comes 0.15mm thickness x 32mm wide x 23.4mm width of inner hole size 2P suit for 21700 batteries spot welding
• High purity pure nickel strip，Purity reached 99.6%
• 5Metes/roll, Suitable for small battery projects, one whole, One continuous piece, no cut and no waste,
• The nickel element is a magnetic metal, with weak magnetic properties, can be attracted by the magnet, Please correct a misunderstanding that being attracted to a magnet is not pure nickel.
• To judge whether it is pure nickel, (1) the sander grinds, there is no spark, (2) put in salt water, it will not rust,
