TUNGSTEN HEAVY ALLOYS FOR
AEROSPACE COMPONENTS
Aerospace demands zero tolerance for error. That’s why leading tier 1 aviation manufacturers and their supply chains trust Wolfmet – one of the world’s leading aerospace tungsten providers.
- Manufacturing in accordance with AS9100, AMS7725F, and ASTM B777-15
- High-density precision engineered components, from prototypes to full production
- End-to end service delivery – parts manufacturing, testing and treatments
SPECIALISTS FOR AEROSPACE
With more than 40 years of experience manufacturing tungsten sourced exclusively from non-conflict origins – giving aerospace procurement teams full supply chain confidence, Wolfmet produce tungsten alloy components for the aerospace sector to very tight tolerances and exacting customer specifications, including:
- balance weights
- ballast weights
- blade weights
- anti-flutter weights
- bucking bars
Due to tungsten’s extremely high density, Wolfmet components offer the use of the smallest possible dimensions for weights, while maintaining the required mass within a confined space. It can ultimately reduce the overall amount of weight used, as it can be positioned more favourably.
TUNGSTEN ALLOY BALANCE WEIGHTS
The balancing of control surfaces, such as ailerons, rudders and stabilisers, and the reduction of vibration in propellers and rotor blades, are critical to flight performance, safety and long reliable service.
Compact Wolfmet tungsten heavy alloy weights give designers the maximum surface area available for control, while preventing flutter and dynamic instability. When balancing individual parts like flight controls, using smaller tungsten heavy alloy components can result in a reduction of the overall weight of an aircraft.
Without proper balancing, the operation of rotor blades and propellers can cause excessive vibration in other parts, degrading flying qualities and possibly reducing component lifetimes. Every element of an aircraft benefits from low vibration levels, so proper static and dynamic balance is essential to ensure a rotor or propeller operates safely and reliably. Wolfmet tungsten alloy balance weights can be manufactured to a wide range of customer requirements that meet the latest industry standards.
Even with the best design and manufacturing techniques, there will occasionally be the need to make small, final adjustments to the balancing of components. Using Wolfmet tungsten heavy alloy to make trim weights allows them to be placed in the smallest spaces; Wolfmet precision-machined trim weights can be produced to exact tolerances and compatible size variations, supporting efficient and flexible final assembly.
TUNGSTEN ALLOY BALLAST
Wolfmet tungsten alloy is ideally suited to aircraft ballast applications where the precise placement of extra weight is required. As ballast can be a removable or permanently installed weight, it can be used to simulate aircraft loading or to bring the centre of gravity into the allowable range.
The loading, or weight and balance, of an aircraft is one of the most important items in the flight test as it affects both performance and stability. Using Wolfmet tungsten alloy as ballast during flight tests allows different payloads to be simulated and small compact weights to be positioned in precise locations.
The centre of gravity of an aircraft must sit within an acceptable range to ensure it can maintain level flight, and is even more critical for helicopters than for fixed-wing aircraft, as improper balance of a helicopter’s load can result in serious control problems. Using Wolfmet tungsten alloy as ballast allows smaller, lighter weight components to be placed in areas where space is restricted, such as the nose or the tail. This brings the centre of gravity within limits at the same time as reducing the overall weight of the aircraft.

Our production facilities ensure rigorous levels of traceability and quality control for our aerospace customers in all aspects of manufacturing and supply chain. Wolfmet is manufactured in accordance with AS9100 and, on request, AMS7725F or ASTM B777-15. In addition, short lead times allow greater production flexibility, which is particularly valuable when creating ballast for flight tests.
Wolfmet is a product of M&I Materials, which is registered with JOSCAR (The Joint Supply Chain Accreditation Register, used by major aerospace and UK defence primes), and complements our impressive list of approvals and certifications, demonstrating our continuous commitment to our customers and the delivery of quality products and technical support.
AEROSPACE STANDARDS
AS9100 Rev D
AS9100 Rev D can be used by organisations across the aerospace sector, including design, manufacturing, maintenance and distributing companies.
AMS7725F
ASTM B777
In addition to defining the chemical, physical and mechanical properties of tungsten alloy, it also looks at composition requirements for tungsten alloy grades.
OUR SERVICE
Due to very high safety standards, the aerospace industry requires rigorous levels of traceability and quality control in all aspects of manufacturing and supply chain. Customers can be assured that we meet all the needs of this industry, including component non-destructive testing (NDT) and treatments for finished parts.
We also offer flexibility of scale, producing small runs of bespoke parts or large quantities for long production runs. Customers can also buy finished components or raw tungsten blocks for final machining themselves.
