Sculpturers, foundries and marine fabricators have come to rely on Atlas Metal Sales for non-ferrous metals. Atlas Metal Sales offers aluminum, brass, bronze, copper, lead, pewter and zinc in its product line.
Atlas maintains one of the largest stocks of silicon bronze shapes in the country and thereby eliminates the need for artisans to wait up to the normal 14 to 16 week lead time on mill-direct shipments. The company’s reputation for quality and competitive pricing is underscored by its saw cutting service as well as shearing and forming. Plus, Atlas Metal is one of only a few distributors that stocks wrought shapes of silicon bronze which come in sheet, plate, rod, bar and tube shapes.
Atlas Metal Sales’ experts know the ins and outs of metals and their application to all kinds of art and sculpture. Rave reviews in Rocky Mountain Fine Art News reported that “when it comes down to it, Atlas Metal Sales has a reputation for being the one to go to when you need metal. End of story.”
The story detailed that art bronze casting in the past, and still in many Italian foundries, used Red Brass, a copper alloy having the nominal chemistry of 85% copper, 5% tin; 5% lead and 5% zinc. It has a universally recognized Copper Development Association (CDA) number of CDA836. Contemporary art foundries normally use either Everdur Silicon Bronze or Herculoy Silicon Bronze. The Everdur is usually called 95-4-1 (CDA873), symbolizing its nominal chemistry of 95% copper, 4% silicon and 1% manganese. The Herculoy is usually called 92-4-4 (CDA876), symbolizing its nominal chemistry of 92% copper, 4% silicon and 4% zinc.
In the wrought form, silicon bronze has a CDA number of CDA655 and its nominal chemistry is 97% copper and 3% silicon. In plate form, it is called Herculoy (an original trademarked name by Revere Copper and Brass). It is understandably confusing to artists in that the “Herculoy” plate is actually closer in chemistry to the “Everdur” ingot than to the “Herculoy” ingot.
