6061 aluminum plate mainly incorporates alloy metals of 1% magnesium and zero.6% silicon, and 7005 plate 4.5% zinc and 1.4% magnesium. T6 is a heat treatment method, appropriate for solution warmness remedy without cold running (straightening and leveling can be done, but does no longer affect the mechanical performance restrict) of the product. T6 is the nominal value of the 20-hour tempering t remedy, and there's also a 10-hour tempering t4 warmth treatment.
The tensile power of 6061 t6 aluminium is 45000 PSI, and that of 7005 51000 PSI. The depth of knuckle down for 6061 t6 is 40000 PSI, and 7005 42000 PSI. On this regard, we will see that 7005 has a higher power than 6061. Nonetheless, The idea that “the larger the range of an alloy name, the better the properties” is deceptive. Despite the fact that some aluminium alloys are more steeply-priced, they do no longer surpass others in a few residences like hardness, lightness, service existence and many others. As an example, 3xxx proves to be heavier than 1xxx aluminium, and 7xxx has much poorer corrosion resistance than 5xxx.
The mechanical homes of 6061 aluminium sheet are medium energy, appropriate plasticity and notable corrosion resistance. 7005, alternatively, can not be welded, and its corrosion resistance is quite poor. It is ordinarily used for CNC slicing. Zinc is the main alloying element in 7005. With a touch magnesium alloy, the material may be heat handled to reap very high electricity. 7005 aluminum plate is lighter and stronger, but 6061 aluminium sheet is extra plastic and corrosion resistant. And the fee of the former is higher.
