1.6mm SIFTIG 5183 Aluminium TIG Rod 1.0kg

The correct aluminium TIG filler rod depends on the parent alloy, the required strength, corrosion resistance, service conditions and whether the welded component will be anodised.

4043 offers excellent weldability, good crack resistance and a smooth weld appearance. 5356 provides higher tensile strength, improved corrosion resistance and is often preferred where the weld will be anodised.

Choose 5356 when higher weld strength is required, improved corrosion resistance is important or the finished component will be anodised.

5183 is commonly used when welding certain high-strength aluminium alloys where greater strength and improved mechanical properties are required compared with 4043 or 5356.

Yes. Matching the filler rod to the parent alloy helps achieve the required strength, corrosion resistance and long-term performance of the welded joint.

Cracking is commonly caused by using an unsuitable filler rod, excessive heat input, contamination or poor joint preparation.

Black soot or discolouration is often caused by poor shielding gas coverage, contamination, incorrect cleaning or excessive heat input.

Store aluminium filler rods in a clean, dry environment and protect them from moisture, dirt, oil and other contamination before welding.

Aluminium TIG filler rods are widely used in motorsport, marine, aerospace, transport, food processing, architectural fabrication and precision engineering.

Before selecting an aluminium TIG filler rod, identify: What aluminium alloy am I welding? Is weld strength the priority? Will the component be anodised? What service environment will it operate in? Is appearance or crack resistance the most important requirement? Answering these questions will help you select the most suitable aluminium TIG filler rod for your application.
