ISO 4506 (Hardmetals — Compression test)

← Back to all standards

ISO 4506 is the compression test method for hardmetals (cemented carbides), determining compressive strength for these very hard, brittle materials. To match this to your program, talk with our team.

What ISO 4506 Covers

It determines the compressive strength of hardmetals such as tungsten-carbide grades, which are strong in compression but brittle, requiring careful specimen preparation and alignment.

How the Test Is Run

A precisely ground hardmetal specimen with flat, parallel ends is loaded in compression to failure under close alignment, and the compressive strength is calculated from the maximum load and cross-section.

Why It Matters

Compressive strength characterizes hardmetal grades for cutting tools and wear parts; high-force capacity and precise alignment are essential for these brittle materials.
