Al-Mg Wire Aluminum-Magnesium Alloy Wire
Lightest Braiding Wire With the Best Weight to Strength Ratio
Product Overview
What This Product Is
Al-Mg wire is aluminium alloyed with 0.3 to 5 percent magnesium, which raises tensile strength and corrosion resistance while keeping the weight advantage of aluminium. It is the standard choice for braided shielding where finished cable weight matters, and for overhead runs in coastal or industrial air. It is supplied in hard H18 temper for tensile applications and soft O temper for braiding. It is not solderable, so it belongs in shielding rather than terminated conductors.

Key Benefits
What It Gives Your Production Line
Lightest Option in the Family
The best weight-to-strength ratio among CCS, CCA, CCAM and Al-Mg, which shows up directly in drum weight.
Corrosion Resistance From the Magnesium
Performs in coastal and industrial environments where plain aluminium degrades.
Braids Cleanly in Soft Temper
Soft O temper gives excellent flexibility for shield braiding without wire breaks.
Two Tempers, Two Jobs
H18 hard temper for strong tensile requirements, O soft temper for flexible braiding work.
Application Scenarios
Where It Is Used
- Braided shielding in coaxial and LAN cables
- Grounding wires and shield mesh
- Overhead transmission lines, especially in coastal or industrial environments
- Automotive and aerospace wiring
- High-frequency signal transmission where weight and flexibility matter
Who It Is For
Who Buys It
- Braiding shops shielding coax and data cable
- Manufacturers of lightweight aerial cable
- Producers supplying automotive and aerospace wiring
Problems It Solves
The Reasons Buyers Move To This Product
Shield Weight Adds Up
A braid covers the whole cable surface. Using the lightest suitable wire cuts finished cable weight across the whole order.
Salt Air Attacks Bare Aluminium
Magnesium content improves corrosion resistance for coastal and industrial installations.
Solderability Must Be Checked First
Bare aluminium does not solder. Where the shield has to be soldered to a connector, choose a copper-clad wire instead.

Manufacturing And Quality Control
How It Is Produced And Checked
Materials are produced to the stated thickness, width and formulation, then slit, wound and packed to the reel or core size ordered. Dimensional checks are made against the specification before dispatch.
Incoming Material
Foil, film, compound or wire checked for thickness and surface condition before processing.
Processing
Coating, lamination, slitting or drawing to the ordered dimension.
Dimensional Check
Width, thickness and roll or reel diameter verified against the specification.
Performance Reference
Shielding attenuation and conductivity referenced to the published figures for the grade.
Packing
Shaft or reel packing in cartons for safe handling and transport.
Customisation Options
What Can Be Changed
- Magnesium content within the 0.3 to 5 percent range
- Hard H18 or soft O temper
- Wire diameter for your braider
- Reel size and reel capacity
Use Guide
Working With It On Your Line
- Specify soft O temper for braiding and hard H18 only where tensile load is the requirement.
- Plan a mechanical or crimped shield termination — this wire does not solder.
- Keep reels away from damp storage so the surface stays clean for braiding.
- Adjust braider carrier tension when switching from copper-clad wire; Al-Mg behaves differently under load.

FAQ
Al-Mg Wire Aluminum-Magnesium Alloy Wire FAQ
Can Al-Mg wire be soldered?
No. Solderability is poor because the surface is bare aluminium. Choose CCA, CCAM or CCS where the shield must be soldered.
What magnesium content is used?
Typically 0.3 to 5 percent magnesium, which improves mechanical strength, corrosion resistance and fatigue performance.
Which temper should I order?
Hard H18 for strong tensile requirements and soft O for flexible applications such as braiding.
Why is it used for aerial cable?
It combines light weight with good tensile strength and corrosion resistance, which suits overhead lines in coastal or industrial environments.
How does conductivity compare with CCA?
Al-Mg runs at roughly 50 to 60 percent IACS against about 60 percent for CCA, so CCA is the better conductor where solderability and conductivity both matter.
