Porcelain alloys are used to fabricate copings and other substructures for crowns and bridges. These metals are cast to create a strong and properly fitting base to support an esthetic porcelain fused to metal (PFM) crown or bridge. A wide range of high noble, noble and base metal compositions can be used for fabricating PFM substructures, so there are numerous alloys that can be used. When considering a porcelain alloy it is important to consider how well the alloy bonds with your prefered ceramic system. Other key attributes of these materials are their specific working properties for casting, along with color and esthetic qualities.

| Description | JP-5 is a noble, palladium-silver porcelain dental alloy. JP-5 has a very small grain size that helps eliminate hot tears and marginal flaking. | High Noble. Ceramic alloy. This is the most noble (thus the most inert) alloy offered in the market, 90% gold and 10% platinum. Like our Bio-C, this | 4all is a nickel-chromium ceramic alloy. Its mechanical and physical properties have been coordinated with conventional feldspar ceramics. | Outstanding performance is a direct result of Acclaim's high yield strength. Averaging 30% stronger than competitive alloys, the increased strength | Aquarius Hard is a clinically proven high-gold ceramic alloy demonstrating outstanding properties. |
