Customer Service

We are committed to exceeding our customers’ expectations by understanding their needs, maintaining open lines of communication, and delivering high quality products on time.


We must wisely use our unique materials and expertise to turn our ideas and technologies into high performance design solutions.


We understand that our success is built on respect for our people, our customers, our technology, and the environments in which we work.


Founded in 1967, ERG Aerospace Corporation has been manufacturing open-celled, solid ligament metal foams called Duocel®. Since then, ERG Aerospace Corporation has been producing foamed metals, carbons, and ceramics for the aerospace, defense, semiconductor manufacturing, biomedical, and scientific industries.

Up until the mid-1990’s, the majority of ERG’s business was sequestered for military applications and included the design and manufacture of critical foam components for reconnaissance satellites, nuclear weapons, ICBMs, and other aerospace systems. With the end of the Cold War, the advanced design and manufacturing technologies that ERG had perfected were then made available for commercial, scientific, and non-classified military applications.

Our primary facility has been in Oakland, CA since 1967, and in 2017 we added another facility for manufacturing operations in Sparks, NV. On January 1, 2022 ERG officially moved its corporate headquarters to Nevada; the California facility will continue to focus on production, engineering, R&D, and precision manufacturing.

ERG is a proud member of the Service-Disabled Veteran Owned Small Business Program.

Bonding and Brazing

It is possible to bond Duocel® products utilizing conventional epoxies and adhesives. Such bonding agents must be compatible to the Duocel® base material and its finished operating environment. Bonding is considered a cost effective alternative to brazing.

Brazing is common among our thermal management products to increase their heat transfer efficiency. Specialized brazing techniques and processes are necessary to ensure the highest quality in our products.

Heat Treating

Duocel® metal foams are available in many heat treatable conditions that are derived from the parent material alloy. For example, ERG Aerospace’s general practice is to provide Duocel® Aluminum in a T6 condition to maximize the strength and durability of the ligaments.

Our dedicated Duocel® foam machine shop covers over 20,000 sq. ft., and is comprised of both manual and CNC machines. Precision machinery coupled with decades of experience by our machinists assures the highest quality Duocel® components and assemblies. Our experience and knowledge in machining open-celled metal foams is unmatched by anyone in the world. We also maintain the unique ability to have our engineering staff co-located in the same building allowing our engineers the flexibility to ensure the Duocel® components meet your required performance criteria.

Duocel® foams are unique materials which require special proprietary fabrication and manufacturing processes that ERG Aerospace corporation has developed over the last 50 years. We work with our customers to define the performance requirements and optimize the Duocel® component design. We then perform the fabrication and machining to ensure the product meets your quality and performance requirements. ERG’s basic and QA systems are based on and certified to AS9100 Rev D, which is the US aerospace version of the international standard ISO 9001. For this reason, we do not sell Duocel® foams in raw or bulk form, but only as finished end item components. This ultimately saves everyone time and money, and results in a superior cost-effective product.

Plating and Chemical Films

Duocel® foam metals are capable of taking on additional plating or chemical film. Plating is used to increase the primary foam’s corrosion resistance, surface finish, thermal transfer properties, and electrical conductivity. Common metal plating includes nickel, gold, silver and platinum. Plating also reduces the cost of having to manufacture the primary foam in an expensive alloy.

Chemical film coatings and anodized foam are also utilized when additional environmental protection is desired such as in space flight applications.

There are many Non-Destructive Testing (NDT) and Destructive Testing (DT) methods that can be employed to quantitatively characterize the Duocel® foam materials.  Some of these tests include airflow, stress/strain, corrosion, X-ray, filtering, salt and leak testing.
