Product Range

Alloy 1070｜Al99.7

• Excellent resistance to chemical corrosion and good crack resistance
• For pure aluminum and dilute aluminum alloys in electrical and chemical applications

Applications: 1xxx-series aluminum, bus bars, switchgear, heat exchangers, metal spraying; electrical, chemical, architectural and food industries; low-strength corrosion-resistant tanks and vessels

Alloy 1100｜Al99.0Cu

• Excellent resistance to chemical corrosion and good crack resistance
• For pure aluminum and dilute aluminum alloys in electrical and chemical applications

Applications: 1xxx-series aluminum, bus bars, switchgear, heat exchangers, metal spraying; electrical, chemical, architectural and food industries

Alloy 2319｜AlCu6MnZrTi

• Primarily for welding alloy 2219
• Offers higher strength and better ductility than 4xxx fillers on 2xxx-series base metals
• Very good stress-corrosion cracking resistance where elevated-temperature performance is required

Applications: Aerospace, high-strength structural applications, military

Alloy 4043｜AlSi5

• Designed for heat-treatable base alloys such as the 6xxx series
• Lower melting point and better fluidity than 5xxx fillers
• Low hot-crack sensitivity when welding 6xxx-series alloys
• Widely used for both welding and brazing; smooth, bright weld beads
• Not recommended where post-weld anodizing color match matters

Applications: 6xxx-series alloys, automotive components, bicycle frames, fitness equipment

Alloy 4047｜AlSi12

• Lower melting point and narrower freezing range than 4043
• Higher fluidity and reduced solidification shrinkage
• Can replace 4043 to add silicon to the weld metal, minimizing hot cracking and increasing fillet shear strength

Applications: Automotive components and body panels; brazing of sheet, extrusions and castings

Alloy 5087｜AlMg4.5MnZr

• High-strength Al-Mg filler with zirconium for grain refinement
• Improved resistance to hot cracking and good weld-metal strength

Applications: Marine construction and repair, shipbuilding and other high-strength aluminum structures, offshore platforms, cryogenic tanks, rail industry

Alloy 5183｜AlMg4.5Mn0.7 (A)

• Engineered to meet the tensile-strength requirements of high-strength Al-Mg alloys
• Standard choice for welding 5083 and 5654
• Also used for 6xxx-series and 5xxx-to-6xxx joints

Applications: Shipbuilding and high-strength structures, cryogenic tanks, rail industry, offshore platforms

Alloy 5356｜AlMg5Cr (A)

• General-purpose filler for 5xxx-series alloys
• The most widely used aluminum welding alloy

Applications: Automotive components, flatbed trailers, general fabrication, electrical industry, rail, shipbuilding

Alloy 5554｜AlMg2.7Mn

• Matching filler for alloy 5454
• Low magnesium content closely matches the base-metal chemistry — suited to sustained service above 65 °C

Applications: Transportation — road tankers and rail tank cars; chemical storage tanks; wheels

Alloy 5556｜AlMg5Mn1Ti

• Higher magnesium and manganese content
• For 5xxx-series alloys requiring higher weld tensile strength, such as 5083 and 5456

Applications: Structural shipbuilding frames, rail industry, trailer industry, automotive parts, containers, military

Alloy 5556A｜AlMg5Mn

• High-magnesium filler for Al-Mg base alloys with up to 5.3% Mg
• Good ductility and improved crack resistance

Applications: General construction and structures, defense

Alloy 5754｜AlMg3

• For Al-Mg alloys with up to 3.0% magnesium
• Good corrosion resistance and the best color match after anodizing
• Widely used in general structures

Applications: Automotive components, storage tanks, shipbuilding
