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
