In the aerospace industry, precision and consistency are critical to manufacturing and assembling safe, reliable aircraft. Aerospace parts must provide long-lasting performance while tolerating humidity, extreme temperatures, and high mechanical stresses. At H&S Manufacturing, we leverage our precision machining capabilities to produce custom sheet metal fabrications that comply with the aerospace industry’s rigorous safety and quality standards. Our AS9100D and ISO 9001:2015 certified facility is equipped to handle everything from prototyping to full production, with services like shearing, punching, precision laser cutting, extruding, notching, and other fabrication techniques.
In this blog, we’ll highlight the applications and benefits of our precision sheet metal fabrication services in the aviation & aerospace industries.
Sheet Metal for Aerospace
Metal materials used in aircraft construction are selected based on several factors, including durability, strength-to-weight ratio, and corrosion resistance. The metal’s structural integrity must also be capable of withstanding exposure to the high pressures and extreme temperatures encountered during flight. Three commonly used sheet metals in this industry are aluminum, stainless steel, and brass.
Aluminum: Aluminum is a lightweight, electrically conductive metal that can be strengthened and enhanced through the addition of various alloying elements. The most popular aluminum alloys in aircraft construction are 7075, 7475-02, and 6061, all of which exhibit excellent resistance to fatigue resistance and damage. Specific aerospace applications of aluminum sheet metal include:

Wing panes
Fuselage
Rudder
Doors and floors
Engine turbines
Cockpit instrumentation
Seats
Exhaust pipes
Stainless steel: Stainless steel is a group of corrosion-resistant iron-carbon alloys containing 10-30% chromium. Because they maintain superior mechanical properties over a wide temperature range, stainless steel alloys are ideal for enduring the harsh conditions of continuous flight. Applications of stainless steel sheet metal manufacturing in the aviation aerospace industry include:
Airframes
Landing gear
Jet engines
Brass: Brass is a copper-zinc alloy with excellent hardness, workability, corrosion, and temperature resistance. This alloy performs well in harsh settings, making it ideal for aerospace environments. Applications of brass sheet metal manufacturing in aircraft construction include:
Wheel and brake components
Landing gear
Cargo doors
Casings for electrical components
Benefits
Aviation sheet metal fabrication is an intricate process that requires precision equipment and close attention to detail. Custom metal stamping and forming techniques are particularly well suited for sheet metal fabricated products since they allow for precise cutting and shaping while eliminating surface defects. Other benefits of metal stamping and forming include:
Affordability: Metal stamping and forming are highly cost-effective, especially for large-scale production runs where the dies can be reused.
High accuracy: The custom dies and tools used for metal stamping ensure excellent precision and tight dimensional tolerances. Cold forming can achieve superior levels of precision since it eliminates any heat-related warping.
To maximize the benefits of sheet metal fabrication, it is important to choose materials that meet the functional and environmental requirements of a given aerospace application. Aluminum, stainless steel, and brass each have distinct advantages:
Aluminum
Excellent strength-to-weight ratio
Resistance to corrosion, UV radiation, and moisture
Malleability
Low cost
Well-documented properties
Simple to inspect
Easy to replace or repair
Recyclable
Stainless steel
Corrosion resistance
Generally stronger and more durable than aluminum
Low maintenance
Aesthetically appealing
Brass
Performs well at high temperatures
Great conductor of heat and electricity
Spark resistance
Corrosion resistance

Aerospace Industry
The aerospace industry is a high-tech industry. Most enterprises in the aerospace industry must comply with one of three specific standards: AS 9100, AS 9110, or AS 9120. A corporation or individual engaged in the design, construction, maintenance, testing, and sale of airplanes, missiles, aircraft parts, rockets, or spacecraft are known as aerospace manufacturers. Airline design and production are the primary focuses of aerospace manufacturing companies. Airliners account for over 60% of all products sold by aerospace manufacturing companies.
Because its principal products, flight vehicles, require millions of different parts, the aerospace industry’s product line is forced to be vast. In addition, to operate and maintain the vehicles, other support systems are required. Military aircraft have the biggest market share in terms of sales, followed by space systems and civil aircraft, with missiles occupying a minor position.
