Magnesium-Aluminum 90° Square

Magnesium-Aluminum 90° Squares are measuring instruments with mutually perpendicular measuring and base surfaces,used to check right angles,perpendicularity,and parallelism.They are also known as angle rulers,straightedges,or 90-degree squares.

Applications:

Inspecting and scribing right angles on workpieces.

Verifying the perpendicularity of component surfaces during equipment installation and adjustment.

Calibrating measuring tools,instruments,and machine tools.

Detecting perpendicularity errors in instrument guideways and workpiece positioning.

Features:

Constructed from high-strength magnesium-aluminum alloy(composed of magnesium,aluminum,zinc,manganese,etc.),complying with GB6092-85 standard.

Superior bending resistance compared to steel and cast iron,with a yield strength of 110 kg/mm².

Rust-proof without oil coating,maintaining accuracy over long-term storage.

Four precision grades(00 to 2)for applications ranging from precision metrology to general industrial use.

Supports light-gap measurement and flip复测methods to eliminate errors.

Lightweight design with dimensions from 630×400 mm to 3000×2000 mm,storable vertically or horizontally.

Maintenance requires only applying industrial oil.

Packaged in wooden crates;custom non-standard models available.
