3004 H14 및 3004 H34는 둘 다 알루미늄 합금입니다., 그러나 그들은 기계적 성질과 성질 지정면에서 다릅니다..

그만큼 “시간” 합금 지정에서 “변형 경화,” 이는 알루미늄이 냉간 가공 또는 변형 경화 공정에 의해 강화되었음을 의미합니다.. 뒤의 숫자 “시간” 변형 경화 정도를 나타냅니다., with higher numbers indicating a greater degree of hardening.

3004 is a popular aluminum alloy that contains both manganese and magnesium, which improve its strength and corrosion resistance. 둘 다 3004 H14 및 3004 H34 have the same chemical composition, ~와 함께 1.0-1.5% manganese and 0.8-1.3% 마그네슘, but they differ in terms of their temper designation.

3004 H14 aluminum coil is in the annealed or soft state, which means it has been fully strain-hardened to a temper of H14. This results in a relatively low strength but high ductility and good formability. It is typically used in applications that require good formability, such as sheet metal work, 제사, and drawing.

3004 H34 알루미늄 코일, on the other hand, has undergone a partial strain hardening process to achieve a temper of H34. This results in higher strength and hardness compared to H14, but with slightly reduced ductility and formability. It is commonly used in applications that require higher strength and better corrosion resistance, such as automotive parts, 압력 용기, and roofing.

In summary, 3004 H14 및 3004 H34 aluminum coils have the same chemical composition but differ in terms of their mechanical properties and temper designation. H14 is in the annealed or soft state, while H34 has undergone partial strain hardening to achieve higher strength and hardness.
