The Basics of Nonferrous Metallurgy

Aluminum Bronzes: Part Two

Aluminum bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion. They are also resistant to corrosion in sea water.

Aluminum Hypoeutectic Alloys

Aluminum-Lithium Alloys: Part One

Aluminum-lithium (Al-Li) alloys represent a significant advancement in lightweight structural materials, offering substantial benefits for aerospace, military, and commercial applications. These innovative alloys provide 7-10% lower density and 10-15% higher modulus of elasticity compared to conventional aluminum alloys.

Aluminum-Lithium Alloys: Part Three

The advantages of aluminum-lithium alloys are numerous and include improved weldability, reduced density, and an improved modulus of elasticity and precipitation hardening.
When considering the stringent requirements of the aerospace industry however, certain properties still require improvement including overall strength and fracture toughness.

Aluminum-Lithium Alloys: Part Two

Industries around the world are seeking to achieve better performance and lighter products with the use of composite materials, but the cost of production with composites pushes the limits of production budgets. Nowhere is this struggle more intense than in the aerospace industry.
But what if a time-tested material could be substantially lightened and improved at the same time? Aluminum alloys, long used and studied by aircraft makers, can indeed be further improved. The results could save more than just fuel and money.

Aluminum-Magnesium (5000) Alloys

Aluminum-magnesium (5000 series) alloys contain magnesium ranging from 0.5% to 13%, offering various performance characteristics based on composition. Low-magnesium variants excel in formability, while high-magnesium alloys provide superior strength and good castability. These alloys are typically manufactured using high-purity aluminum (99.7% or higher) to maximize corrosion resistance and reflectivity.
