2013 Aluminum Alloy Extrusion for Low Cost Aircraft Structures
[New Product Introduction]

High strength aluminum alloy 2013 extrusion has been developed as an alternative to 2024 alloy that is typically used for aircraft structures. 2013 has equivalent strength characteristics of 2024 alloy, and can be extruded to thin complex shapes because of its excellent extrudability. Therefore, 2013 can reduce assembly and machining cost by means of an integrated structure.

Development of Low Cost Aluminum Tapered Handlebar for Motorcycles

An alloy created using  a large amount of zinc while reducing the amount of the copper, which deteriorates the extrusion productivity.  However, a large amount of zinc decreases the stress corrosion cracking resistance. Therefore, in order to obtain a metallic structure favorable to the prevention of stress corrosion cracking, the mandrel extrusion was applied for the pipe manufacturing method, and heat treatment condition and swaging condition were optimized. With this development, we have made it possible to manufacture the tapered handlebar made of high strength aluminum alloy with less weight by 20% and with lower cost by 30% than those of the conventional handlebar.

Development of Type 204 CU Stainless, A Low - Cost Alternate to Type 304

For the development of Type 204Cu Stainless, to achieve lower cost than Type 304, Modified Type 201, with 6% lower nickel content than Type 304 was selected as the base alloy.  To achieve similar formability and work hardening rate as Type 304, copper was the key elemental addition to Modified Type 201. To achieve similar corrosion resistance as Type 304, a careful balance of alloying elements which include chromium, molybdenum, nitrogen and nickel was necessary. Data is presented comparing the strength, work hardening rate, formability, and corrosion resistance of the two alloys. Potential uses for Type 204Cu  are discussed.

Pacific Northwest National Laboratory, April 1, 2016

RICHLAND, Wash. – An improved titanium alloy — stronger than any commercial titanium alloy currently on the market — gets its strength from the novel way atoms are arranged to form a special nanostructure. For the first time, researchers have been able to see this alignment and then manipulate it to make the strongest titanium alloy ever developed, and with a lower cost process to boot.

They note in a paper published on April 1 by Nature Communications that the material is an excellent candidate for producing lighter vehicle parts, and that this newfound understanding may lead to creation of other high strength alloys.

Researchers at the Department of Energy's Pacific Northwest National Laboratory knew the titanium alloy made from a low-cost process they had previously pioneered had very good mechanical properties, but they wanted to know how to make it even stronger. Using powerful electron microscopes and a unique atom probe imaging approach they were able to peer deep inside the alloy's nanostructure to see what was happening. Once they understood the nanostructure, they were able to create the strongest titanium alloy ever made.

New alloy of steel created that's as  light as titanium
February 12, 2015
By altering metal alloy at a nanoscale level,  the Graduate Institute of Ferrous Technology (GIFT) researchers at Pohang University of Science and Technology in South Korea have developed a new alloy that has the strength of steel and the lightness of titanium alloy. Made from an amalgam of steel, aluminum, carbon, manganese, and nickel, the new alloy promises to be low-cost and readily available due to its mix of common minerals.

IBC’s cost-effective, high-performance castable beryllium-aluminum alloy
OCTOBER 16, 2013
Beryllium is a relatively rare element that is very light, extremely stiff and stronger than steel, x-ray transparent, non-magnetic and non-sparking, and melts at 2,307°C. Aluminum melts at a much lower 660.32°C. Pure beryllium plays a strategic role in the nuclear, aerospace and defense industries, and is widely utilized as an alloy in telecom, computing, electronics, medical, oil and gas, and automotive industries. IBC produces a family of patented beryllium-aluminum alloys — marketed as Beralcast® — that overcomes the limitations of pure beryllium and existing powder metal beryllium-aluminum products, while retaining the benefits of the two metals. IBC’s Beralcast offers a cost-effective solution for high performance applications by combining beryllium’s lightweight and high stiffness with aluminum’s excellent processing characteristics and low cost. Beralcast is produced using a process similar to conventional vacuum investment casting and can be cast into complex shapes that require minimal machining.

Low Cost Aluminum Foams For Industrial Application
Date: July 23, 2009
In this process, the production of aluminum foam is a continuous process, and leads to significant cost reductions since this is a cheaper product than titanium hydride and other currently used foaming agents, it can multiply the many applications of these materials.

The main applications of aluminum foams are found in the automotive industry (impact, acoustic and vibration absorbers), the aerospace industry as structural components in turbines and spatial cones, in the naval industry as low frequency vibration absorbers, and in construction industry as sound barriers inside tunnels and as fire proof materials, structure protection systems against explosions and even as decoration.
