A solder that is used in dentistry, has a high fusion point, and is stronger and more tarnish-resistant than softer, low-melting-point solders. This class of solders has increased compressive strength and reduced tensile strength. The increased strength is a result of increased platinum or palladium content within the alloy. This class of alloys is used for appliances that span large distances in the oral cavity.
