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).
If the gold layer is 12 kt or higher, the minimum layer of karat gold in an item stamped gold-filled marks must equal at least 1 ⁄ 20th the total weight of the item. The most common stamps found on gold-filled jewelry are 1 ⁄ 20th 12kt GF and 1 ⁄ 20th 14kt GF. Also common is 1 ⁄ 10th 10kt. These standards are for modern gold-filled items.
The Main difference between the two is that the special-order piece is made in precious materials, while often a model is not, and the need for exacting precision is nowhere near as high as in model making. Generally, the special order jewelers take a design, either their own or a customer's, and turn it into a piece of finished jewelry from ...
The BIS system of hallmarking of gold jewellery began in April 2000. The standard specifications governing this system are IS 1417 (grades of gold and gold alloys, jewellery/artefacts), IS 1418 (assaying of gold in gold bullion, gold alloys and gold jewellery/artefacts), IS 2790 (guidelines for manufacture of 14, 18 and 22 carat gold alloys only ), IS 3095 (gold solders for use in manufacture ...
There are three basic techniques that may be used to attach granules to a metal surface: hard soldering, fusing and colloidal soldering. The metals used in granulation are usually gold and/or silver alloys of high purity – alloys below 18 kt. gold and sterling silver being unsuitable. With each technique, the process begins with the making of ...
Gold content in AuAl 2 is around 79% and can therefore be referred to as 18 karat gold. Purple gold is more brittle than other gold alloys (called the "purple plague" when it forms and causes serious faults in electronics [14]), as it is an intermetallic compound instead of a malleable alloy, and a sharp blow may cause it to shatter.

Grills are made of several types of metal (often silver, gold or platinum) that are sometimes inlaid with precious stones; they are generally removable, though some may be permanently attached to the teeth. [5] Gold grills can be made from 10-karat, up to 24-karat gold. The gold can be tinted yellow, white and rose color. [6] [dubious – discuss]
