Magnesium-Aluminum Alloy Parallel Straight Edge

Magnesium-Aluminum Alloy Parallel Straight Edge

The Magnesium-Aluminum(Mg-Al)Alloy Parallel Straight Edge is a high-precision measuring and calibration tool designed for industrial metrology,quality control,and machine tool alignment applications.Engineered with an optimal blend of magnesium and aluminum alloys,this straight edge combines exceptional rigidity with lightweight properties,offering superior performance in demanding workshop environments.

Key Features&Technical Specifications

Advanced Material Science

Ultra-Lightweight Construction:60%lighter than traditional cast iron straight edges(density:~2.0 g/cm³)while maintaining≥85%of the stiffness.

Zero Thermal Deformation:Coefficient of thermal expansion(CTE)of 24.5μm/m·°C(20–100°C range),ensuring stability in temperature-fluctuating environments.

Corrosion-Resistant:Anodized surface treatment(MIL-A-8625 Type III)for prolonged service life.

Precision Engineering

Flatness Tolerance:Grade AA(±0.001mm/300mm)to Grade A(±0.003mm/300mm)per ISO 8512-1.

Parallelism:≤0.005mm across all working edges(certifiable to NIST traceable standards).

Modular Lengths:500mm to 3000mm(customizable in 250mm increments).

Ergonomic Design

Non-Slip Rubberized Edges:Shore A70 grip pads for secure handling.

Lifting Grooves:Integrated handles for safe transport of long-span models(≥2000mm).

Compliance&Applications

Standards:Complies with DIN 874(precision straight edges)and ANSI/ASME B89.3.7(flatness verification).

Typical Uses:

Machine tool bed alignment(CNC/VMC)

Optical comparator reference edges

Composite material layup verification in aerospace

Why Choose Mg-Al Alloy?

Vibration Damping:30%better harmonic dissipation than steel,reducing measurement"chatter."

Non-Magnetic:Ideal for EDM and MRI-compatible environments.

Cost-Effective:40%lower lifecycle cost vs.granite equivalents due to durability.
