Is the mobile phone frame stainless steel, magnesium-aluminum alloy or aluminum alloy?

Personally, from the perspective of anti-fall, the frame of mobile phone is still stainless steel, because stainless steel is harder than aluminum alloy, so it has stronger anti-aging ability.

Therefore, the hardness of stainless steel frame is higher than that of aluminum alloy frame, so it is more resistant to falling and durable.

The aluminum alloy frame has good fall resistance and aesthetics. Pay attention to the appearance when choosing a mobile phone, other materials are irrelevant.

Both are good, because they are used differently, and there is no better difference. Mainly to see what they are used for, and choose materials according to their uses. In terms of price, stainless steel is expensive and aluminum alloy is cheap. Stainless steel has higher hardness than aluminum alloy.

Features: aluminum alloy: low density, but relatively high strength, close to or exceeding high-quality steel. Stainless steel: good weldability and strong corrosion resistance. Most stainless steel products need good corrosion resistance. Hardness: stainless steel has low density, but high strength, close to steel and good plasticity.
