Aluminum is a paramagnetic metal with a white-silver hue, very light. Density = 2.7 g / cm³. At t ° 658 — 660 ° C (depending on the purity), aluminum melts, Brinnel hardness is within 24−32 kgf / mm². Sv — short-term strength = 10−12 kg / mm2, and in the alloy Sv = 38−42 kg / mm2. High ductility is 50% for pure aluminum and 35% for technical aluminum.
Automotive aluminum alloys. Classification
Depending on the purpose, automobile aluminum alloys are divided into:
Casting alloys in terms of chemical composition are divided into five groups
- doped with magnesium (4.6−11.5% Mg); brands: AL8, AL13, AL22, AL23, AL23−1, AL27, AL27−1, AL28 and AL29;
- Copper-doped (4−14% Cu); brand: AL7, AL7B and AL19;
- Copper doped with copper (1−8% Cu) and silicon (4−6% Si and grades: AL3, AL3B, AL5, AL6, AL10B, AL14B and AL15B, so-called silumins (contain 6−13% Si);, AL4, AL4B, AL9 and AL9B;
- other alloys: AL1, AL11, AL16B, AL17B, AL18B, AL20, AL21, A24, AL25, AL26 and ALZO.
