3004 H14 ve 3004 H34'ün her ikisi de alüminyum alaşımlarıdır, ancak mekanik özellikleri ve temper atamaları açısından farklılık gösterirler..
bu “H” alaşım tanımlamasında şu anlama gelir: “gerilimle sertleştirilmiş,” bu, alüminyumun bir soğuk işleme veya gerinim sertleştirme işlemiyle güçlendirildiği anlamına gelir. Bundan sonraki sayı “H” gerinim sertleşmesinin seviyesini gösterir, 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. İkisi birden 3004 H14 ve 3004 H34 have the same chemical composition, ile birlikte 1.0-1.5% manganese and 0.8-1.3% magnezyum, 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, dönen, and drawing.
3004 H34 alüminyum bobin, 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, basınçlı kaplar, and roofing.
In summary, 3004 H14 ve 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.
