Fusion welding, using a platinum or alloy filler rod of the same composition as the parent metal and a shielded electric arc or an oxy-hydrogen flame (an oxy-acetylene flame may cause carbon pick-up by the molten metal). The weld fillets are then cold hammered to the contours of the sur...

A piece of platinum metal with a density of 21.5g/cm3 has a volume of 4.49 cm3. What is its mass? Multiplication for Mass Value: The multiplication of the unit 1 g/cm3 with the unit 1 cm3 will give us the number of grams of a substance. The...
There are 96 approved PG (platinum group) — mineral species and more than 500 unidentified PG-phases on record. In addition, over 20 non-PG-minerals contain varying concentrations of one or more of the six platinum group elements. The PG-minerals commonly have cubic symmetry and density value...
Many harnesses were so encrusted with gold, platinum, silver and precious stones as to entirely hide the leather beneath. View in context Of platinum, too, which is more expensive than gold, it uses one thousand pounds a year in the making of telephone transmitters. View in context Rare and...
Gold: gold jewelry in order to overcome the hardness difference, single color, easy to wear, the pattern is not delicate shortcomings, the development of gold alloy jewelry: gold jewelry is characterized by low cost, less the amount of gold, ...
This study examined the age-hardening by miscibility limit in a multi-purpose dental gold alloy containing platinum. The hardness increased rapidly in the initial stage of the aging process, reached the maximum value, then decreased continuously with aging time. The significant hardness increase result...
