Aluminum fasteners have become essential in industries where weight reduction, strength, and corrosion resistance are critical — from automotive and marine to aerospace and precision machinery. However, not all aluminum alloys perform equally. The most widely used grades — 2024, 6061, and 7075 — each offer distinct mechanical, chemical, and economic properties that influence fastener performance. In this comprehensive guide, Welleshaft’s engineering team breaks down how to choose the best aluminum alloy for your fasteners, comparing 2024 vs 6061 vs 7075 aluminum fasteners across strength, corrosion resistance, machinability, and cost. Whether you’re sourcing aerospace-grade aluminum bolts or custom aluminum fasteners for automotive assemblies, this article will help you make an […]
