Title:
MAGNESIUM-BASE ALLOY SCREW
Document Type and Number:
Japanese Patent JP2011141032
Kind Code:
A
Abstract:

To provide a screw made of a magnesium-base alloy excellent in strength.

The magnesium-base alloy screw is made of the magnesium-base alloy containing Al by 5.5-12 mass%. The magnesium-base alloy screw is formed by forming and shaping a drawn material wire made of the magnesium-base alloy obtained by drawing. The average crystal grain size of the wire is ≤10 μm, and the maximum crystal grain size is ≤15 μm, and moreover, the tension strength of the screw is ≥220 MPa. Furthermore, the magnesium-base alloy may contain one or more kinds selected from Mn: 0.1-2.0%, Zn: 0.1-5.0%, and Si: 0.1-5.0% by mass%.
