Legor® OG445C - Yellow Alloy 14-18 KT Casting

Legor's OG445C is a soft yellow alloy for lost wax casting. This is a versatile product which possesses an excellent quality: price ratio. Offers compact surfaces and reduced shrinkage porosity. Possesses antioxidant properties and good fluidity. OG455C is an alloy for lost-wax casting, designed specifically for open systems. If a more yellow-greenish color is required, the alloy composition can be modified with the addition of silver, according to the following ratio: Au: 585 / Ag: 75 / OG445C: 340. After this modification, liquidus temperature (Tliq.) will be about 870°C. Casting and graining temperatures reported in this technical sheet will be consequently reduced of about 20°C. MSDS.
