DENT RESISTANCE. It is commonly used as an alternative to aluminum alloys due to its high strength to weight ratio. This datasheet will elaborate on the properties and applications of this alloy. Chemical Composition. AZ31B-O magnesium is AZ31B magnesium in the annealed condition. AZ31B magnesium alloy were studied using electrochemical solution potential-time and extension-time oscillographic curves obtained simultaneously. The power required per cubic centimeter of metal removed varies from 9 to 14 watts per minute depending on machining operation. AZ31B-H26 alloy is a version of the base AZ31B magnesium alloy that is partially annealed and partially strain hardened. Magnesium AZ31B-H24 is a partially annealed and partially strain hardened version of AZ31B, with the version “0” having only an annealed treatment and the H26 version fully hardened and partially annealed. Magnesium Alloy AZ31B Properties. Magnesium AZ31B-O alloy is available in the form of annealed sheets. This alloy is mainly used in applications that require lower weight and high strength. Certainly the most widely available of the magnesium grades, AZ31B is produced in a wide variety of shapes from sheet and plate through bar forms. AZ31B, like all magnesium alloy sheet and plate, machines faster than any other metal. Grade Description Specification; AZ31B: ROD: AMS-QQM-31, ASTM-B-107: AZ31B-F: TOOLING PLATE: AZ31B-0: SHEET AND PLATE: AMS 4375, AMS-QQM-44: AZ31B-H24: SHEET AND PLATE Due to these differences, the H26 temper finds slightly different use than similar materials or can be used in combination with them. Details Chemical Data, Mechanical Properties and Specifications for Magnesium Alloy AZ31B-H24. It has the lowest strength and highest ductility compared to the other variants of AZ31B magnesium. Providing the geometry of the part allows, the limiting factor is the power and speed of the machine rather than the quality of the tool material.

When compared to other versions of the same alloy, AZ31B-H26 has very high strength and stiffness, but lower ductility. The following table provides the chemical composition of magnesium AZ31B-O alloy.
