The difference between aluminum alloy and lead alloy, 1: aluminium alloy is very light, flexibility is very good, not easy fracture/jump. 2:Lead alloy are heavier, no flexibility, easy to fracture/jump. 3:And cheap lead alloy, USES a cheap way of model casting, so, in shape, edge, surface color treatment, are far behind and rough.Our products are the real super light aluminium alloy CNC numerical control processing, a lot of time overall. Please don't use cheap price of the product compared to our products.
