Oerlikon Alurod AlMg4.5MnZr description: ALUROD AlMg4.5MnZr is a 5087 type aluminum solid TlG welding rod depositing Al-4.5Mg0.8Mn0.1Zr weld metal. Suitable for use with Ar, or Ar+He mixed shielding gases. ALUROD AlMg4.5MnZr is suitable for the welding of Al 3-5% Mg alloys. The weld metal has an excellent resistance to hot cracking due to the zirconium addition. Zr promotes grain refinement and improves the mechanical properties and corrosion characteristics. For special request ALUROD AlMg4.5MnZr is available with LRS (Lloyd's Register) approval.
