Brownells Cerrosafe Chamber Casting Alloy

Description

Product Overview

Brownells Cerrosafe Chamber Casting Alloy is a precision low-melting alloy used to create accurate casts of firearm chambers for gunsmithing tasks such as verifying dimensions and assisting with die, reamer, or gauge making. Cerrosafe’s predictable dimensional change during cooling is a key reason toolmakers use it for tight, chamber-specific measurements.

Key Features

• Low-melting Cerrosafe alloy for straightforward chamber casting
• Returns to exact chamber size after about 1 hour of cooling
• Predictable long-cool expansion for consistent measurement workflows
• Standard melting range of 158 F - 190 F for controlled melting and pouring

For accurate chamber casts that toolmakers can build around, Cerrosafe is a go-to choice from the bench to the shop floor.
