3000 series aluminum and can be called anti-rust aluminum, our 3000 series aluminum production process is more excellent. 3000 series aluminum is mainly composed of manganese. Content of between 1.0-1.5. Is a series of anti-rust function better, the price higher than the 1000 series, is a more commonly used alloy series. Strength of 3005 aluminum about 20% higher than in 3003, corrosion resistance is better.
