3A21 Aluminum Sheets Mill Polished Aluminium Plate 3mm For Boat Making
3A21 Aluminum Sheet For Boat Making Cold Rolled Aluminum Alloy Sheet 3mm
Performance of 3A21 Aluminum Sheet:
3A21 aluminum sheet is also a typical 3 series Al-Mn rust-proof alloy, but it’s not difficult to find that it has the letter A in its name. In fact, the A here represents an improvement on the original pure aluminum, so as to develop 3A21 aluminum instead of aluminum alloy. Similarly, 3A21 aluminum sheet is also a non-heat treated alloy, and can only be enhanced by cold machining. Besides, due to the addition of the main alloy Mn, 3A21 aluminum alloy has the characteristics of excellent corrosion resistance, good formability and weldability, and appropriate strength, etc., so it is widely used in both these properties and the conditions requiring higher strength than the 1-series alloy, or the low-load parts working in liquid and gas medium, etc.
