Description

Wood's Metal GR is a specialized low-melting-point alloy, also known by its CAS number 96093-98-6. This high-purity grade is engineered for applications demanding exceptional consistency and minimal metallic impurities. It is an essential material for manufacturers and researchers in electronics, precision casting, and safety device production who require reliable thermal and electrical properties.

Application

• Fusible Alloys & Safety Devices: Core component in thermal fuses, sprinkler heads, and fire door releases due to its predictable, low melting point.
• Precision Casting & Molding: Used as a sacrificial pattern or mold material in complex investment casting processes for aerospace and medical components.
• Electronics & Semiconductor: Employed in soldering, sealing, and as a temperature-sensitive bonding agent for delicate electronic assemblies.
• Laboratory & Research: Serves as a constant-temperature bath medium, a metal matrix for sample preparation, and in physics demonstrations.
• Tooling & Fixturing: Utilized for temporary fixturing, clamping, or anchoring of fragile parts during machining or assembly.
• Specialized Plumbing & Piping: Acts as a fusible plug in pressure vessels and gas systems for over-temperature protection.
