Gold–aluminium intermetallic have different properties from the individual metals, such as low conductivity and high melting point depending on their composition. Due to the difference of density between the metals and intermetallics, the growth of the intermetallic layers causes reduction in volume, and therefore creates gaps in the metal ...
6061-T6 aluminium standard heat treating process. T6 temper 6061 has been treated to provide the maximum precipitation hardening (and therefore maximum yield strength) for a 6061 aluminium alloy. It has an ultimate tensile strength of at least 290 MPa (42 ksi) and yield strength of at least 240 MPa (35 ksi).

6060 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is much more closely related to the alloy 6063 than to 6061.The main difference between 6060 and 6063 is that 6063 has a slightly higher magnesium content.
6082 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is one of the more popular alloys in its series (alongside alloys 6005, 6061, and 6063), although it is not strongly featured in ASTM (North American) standards.
The standard gold bar held and traded internationally by central banks and bullion dealers is the Good Delivery bar with a 400 ozt (12.4 kg; 27.4 lb) nominal weight. However, its precise gold content is permitted to vary between 350 ozt (10.9 kg; 24.0 lb) and 430 ozt (13.4 kg; 29.5 lb). The minimum purity required is 99.5% gold.
Eldorado Gold increased the gold production from 64,298 ounces in 2005 to 632,539 ounces in 2010, despite the closure of the São Bento in 2007, [3] by bringing Kişladağ into production in 2006, acquiring the Toronto Stock Exchange-listed Afcan Mining Corporation for its Tanjianshan Mine which it had acquired two years previous from Sino Gold ...
