7015 alloy aluminium, alformasi aluminium sareng alloy aluminium cacad A.S. Paduan aluminium dibagi kana dua kategori: alloy aluminium tuang, anu dianggo dina kaayaan cor; alloy aluminium cacad, anu tahanngolah tekanansareng ngagaduhan sipat mékanis langkung luhur tibatan nagara cor. Éta tiasa diolah kana sababaraha bentuk sareng spésifikasi bahan alloy aluminium. Hal ieu ilaharna dianggo dina pembuatan alat-alat penerbangan, barang hirup sapopoé, panto sareng windows pikeun konstruksi, sareng sajabana â— Bandingkeun standar: Alcoa (AA) 7015 â - Komposisi kimia: Al Al (mnt.): Sisa Si: â ‰ ¤0.20 Fe Fe: â ‰ ¤0.30 Cu Cu: 0.06-0.15 Mn Mn: â ‰ ¤0.10 Mg Mg: 1.3--2.1 Cr Cr -2.1 Kromium Cr: â ‰ ¤0.15 Seng Zn: 4.6--5.2 Zirconium Zr: 0.10--0.20 Titanium Ti: â ‰ ¤0.10 Unsur sanés anu teu dieusian: masing-masing: â ‰ ¤0.05; total: â ‰ ¤ 0.156061 alloy aluminium mangrupikeun paduan aluminium kualitas luhur anu dihasilkeun ku perlakuan panas sateuacanna manjang, kakuatanana henteu tiasa dibandingkeun sareng séri 2XXX atanapi séri 7XXX, tapi ciri magnesium sareng paduan silikon na, gaduh unggulanngolahna performance, excellent welding characteristics and plating, good corrosion resistance, high toughness and no deformation afterngolahna, dense material without defects and easy to polish, easy to color film, excellent oxidation effect, and other excellent characteristics. The main alloying elements of 6061 aluminum alloy are magnesium and silicon, and form Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy without making its corrosion resistance significantly reduced; there is a small amount of copper in the conductive material to offset the bad effect of titanium and iron on the conductivity; zirconium or titanium can refine the grain and control the recrystallization organization; in order to improve the kabisaan, lead sareng bismuth tiasa ditambihan.
