ACCUALA39310 - Ampcotrode 150 Aluminum Bronze TIG Filler Rod 2.5mm

Premium Aluminum Bronze Alloy for Industrial Wear Applications

The Ampcotrode 150 TIG Rod (2.5mm) represents the pinnacle of aluminum bronze filler metals, designed specifically for high-demand industrial maintenance and fabrication. Manufactured by Ampco Metal, this alloy (AWS ERCuAl-A2) is engineered to provide exceptional mechanical properties, combining high yield strength with ductility. It is primarily utilized for overlaying bearing surfaces where resistance to metal-to-metal wear is critical, as well as for joining dissimilar metals such as mild steel to copper alloys.

Metallurgically, Ampcotrode 150 is a copper-aluminum alloy containing iron, which refines the grain structure and enhances strength. This composition results in a deposit hardness of approximately 140-160 Brinell (BHN), making it significantly more durable than standard deoxidized copper or silicon bronze fillers. It excels in applications involving heavy loads, friction, and abrasive wear, such as rebuilding worn shafts, valve seats, and gear teeth. Furthermore, its inherent corrosion resistance makes it suitable for components exposed to salt water or certain chemical environments.

For the industrial MRO specialist, this 2.5mm rod offers precise control during the Gas Tungsten Arc Welding (GTAW) process. The rod flows smoothly under 100% Argon shielding gas, producing sound, porosity-free welds when base metals are properly prepared. It is an essential inventory item for machine shops and heavy equipment repair facilities dealing with pumps, marine hardware, and hydraulic components. The ability to weld dissimilar metals also allows for the fabrication of composite parts, utilizing the strength of steel with the bearing properties of bronze.
