1, zotayidwa za aluminiyamu zimapendekeka kuti muwone zotayidwa za aluminiyamu ndi ukalamba.Zinthu zakuthupi ndi ukalamba sizofanana, mphamvu sizofanana.

2. Aloyi wambiri wa aluminium:

Madzi zotayidwa 5A50 kwamakokedwe mphamvu: 265MPa; kwamakokedwe mphamvu ya 3A21: <167MPa;

Kwamakokedwe mphamvu ya duralumin 2A11: 370MPa; kwamakokedwe mphamvu ya 2A12: 390 ~ 420MPa; kwamakokedwe mphamvu ya 2A13: 315 ~ 345MPa;

3.Kulimba kwamakina a aluminium yoyera yamakampani: 80 ~ 100MPa;

4. Mphamvu yopendekeka imatanthawuza kuti gawo lakumtunda la membala ndi gawo la extrusion ndipo gawo lakumunsi ndilo malo olimba pomwe membala wagwada.
