ASTM B93/B93M is the ASTM standard that covers magnesium alloys in ingot form for sand castings, permanent mold castings, and die castings. It provides a technical basis for identifying and supplying ingot materials used to produce cast magnesium parts, helping buyers and producers align on material expectations. By defining this product form and application context, the standard supports more consistent procurement, quality control, and specification compliance across foundry operations.

What is ASTM B93/B93M?

This ASTM standard is a specification for magnesium alloy ingots intended for casting applications. Its focus is on the material supplied before casting, not on the finished casting itself. In practice, ASTM B93/B93M helps establish a common reference for magnesium alloy ingot used in sand castings, permanent mold castings, and die castings. That makes it a useful technical document for material selection, ordering, and verification within casting supply chains.

Where is ASTM B93/B93M used?

ASTM B93/B93M is commonly used in foundries and materials procurement workflows where magnesium alloy ingots are purchased for casting production. It is relevant anywhere magnesium cast components are made using sand casting, permanent mold casting, or die casting processes. The standard supports communication between suppliers, purchasers, and production teams by giving them a shared specification for ingot form material used in cast part manufacturing and related quality checks.

Why is ASTM B93/B93M important?

This standard matters because it helps reduce uncertainty when specifying magnesium alloy ingots for casting use. ASTM B93/B93M supports consistency in purchasing, material acceptance, and production planning by giving users a recognized ASTM reference for the supplied alloy form. That can help improve traceability, streamline compliance reviews, and lower the risk of receiving material that does not match casting requirements or internal quality expectations.
