Material selection for aerospace and defense programs must account for performance, traceability, and specification compliance. Lewis Brass & Copper helps customers source aerospace-grade metal alloys that match the applicable specification and intended service environment. 

Our inventory includes copper-based products in standard mill forms, along with tubing and precision-cut stock for machining or further processing. Customers can also request assistance with corrosion-resistant alloys, non-magnetic aerospace materials, or AMS spec brass and copper when the application requires a defined material standard. 

As an established bronze, copper, and brass supplier, Lewis Brass & Copper helps customers find materials that align with their stated aerospace or defense specifications. This material support can simplify the path from specification review to delivery.

Applications in the Aerospace and Defense Industry

Copper-based alloys support aerospace and defense systems that require controlled material properties, precise dimensions, and dependable documentation.

Electrical Connectors and Grounding Components

Copper and specified high-conductivity brass alloys may be used in electrical connectors when they meet the design’s conductivity requirement. 

Fasteners and Static-Control Hardware

Specified copper-based alloys may be used for aerospace fastener materials or antistatic metal fasteners when the application requires electrical continuity.

Bearings and Bushings

Selected bronze alloys are often used for bearings and bushings because they can perform well under repeated movement and friction.

Hydraulic and Fluid-Control Systems

Brass or bronze bar and tubing can be machined into fittings and valve components for aerospace fluid-control assemblies.

Thermal-Management Equipment

Copper and specified heat-resistant copper alloys can support cooling components where heat transfer affects system performance.

Sensitive Electronics and Instrumentation

A non-magnetic copper alloy may be suitable for instrument parts or electronic components that require controlled magnetic response.

Spark- and Static-Sensitive Equipment

Properly specified antistatic aerospace materials may be considered for non-sparking hardware in environments where ignition risk must be carefully managed.

Naval and Shipboard Defense Systems

When the required alloy and form are available, naval brass for marine applications may be used for shipboard parts exposed to saltwater. 

Benefits of Copper-Alloy Materials in Aerospace and Defense

Lewis Brass & Copper products give aerospace and defense buyers access to copper-based materials with useful conductivity, machinability, and wear properties. Corrosion-resistant alloys may support parts exposed to moisture or marine service when the selected grade matches the environment. Bronze can be a practical choice for components that experience friction. Naval brass for marine applications offers another option for shipboard equipment that must tolerate saltwater exposure.

Material selection still depends on the governing drawing and required specification. Lewis Brass & Copper helps customers evaluate aerospace-grade metal alloys and review possible material substitutions. Stocked forms and cut-to-length service can also reduce preparation before machining. Requests for military-grade brass alloys are handled according to the stated military, ASTM, or AMS requirement rather than treating “military grade” as a single material category.

Why Lewis Brass & Copper for the Aerospace and Defense Industry

Lewis Brass & Copper brings more than six decades of alloy experience to aerospace and defense material sourcing. As a brass, bronze, and copper distributor, we supply standard forms, custom sizes, and precision-cut material for demanding programs. Blanket orders and volume agreements can help customers plan recurring material requirements without carrying excess inventory.

Our team can assist with alloy selection and application matching while helping customers review machinability or possible substitutions. Customers can provide the required alloy, temper, dimensions, and material standard so our team can review availability and documentation needs before quoting.

Lewis Brass & Copper focuses on material supply and processing rather than finished-component manufacturing. Material certifications and dimensional requirements can be addressed during quoting. Established mill relationships also support non-stock sourcing and special orders.

Frequently Asked Questions

Yes. Lewis Brass & Copper can help identify or source copper-based alloys for applications that require low magnetic permeability or non-magnetic behavior.

Copper and many brass or bronze alloys are generally non-ferromagnetic, but magnetic response can still vary by alloy and condition. Processing methods or surface contamination may also affect the finished part. Customers should provide the required specification and any permeability limit when requesting metal alloys for sensitive aerospace applications. 

Final approval should come from the customer’s engineering or quality team because a broad material description cannot confirm suitability for every defense-electronics environment.

Yes. Lewis Brass & Copper offers precision cutting and cut-to-length service that can support small-batch aerospace prototyping.

Service availability depends on the material form and required dimensions. Tolerance needs should be provided before quoting so the team can confirm what is available. Precision-cut material may reduce preparation before a customer begins machining or testing. Lewis Brass & Copper supplies and processes raw material rather than producing finished prototype components.

Lewis Brass & Copper can support specified traceability requirements through available mill certifications and related order documentation, but the exact documentation package must be confirmed before ordering.

Documentation can vary by product and material source. Customers should identify any lot-control, marking, or record-retention requirements during quoting. Mill test reports or material certifications may be available for qualifying products.

Certain bronze alloys are well suited to aircraft components because they can resist wear under repeated movement.

This property can make bronze useful for bearings, bushings, and sleeves. Some grades also offer corrosion resistance for demanding operating environments. The correct bronze depends on the load and expected service conditions. Lubrication requirements and the mating material may also affect selection. Engineers should confirm the alloy against the applicable drawing before approving it for production.

Yes. Lewis Brass & Copper can supply or source materials that meet specified AMS requirements when the required product is available.

AMS specifications apply to defined alloys, forms, and conditions. They should not be treated as broad approvals for every brass or copper product. Customers should provide the complete AMS designation and required revision. Documentation or testing requirements should also be stated before ordering. Lewis Brass & Copper can then review available stock or pursue a special mill order for qualifying AMS spec brass and copper.
