Forging, Machining &

Aluminium

(

Expert in forging aluminiumThanks to its recognized know-how for more than 50 years, Lebronze alloys is today a major player in die-forging and machining of aluminium components.

From product development to the delivery of final ready to assemble parts. Our engineering office and workshops are made available to conduct high level research and development programmes. We will support you in determining solutions but also in the concept and development of new products.

By supporting you in the early stages including the analysis of your specifications, we have the possibility, if necessary, to propose alternatives to existing solutions that meet both your costs and quality objectives.

Many applications• Building (mechanical components)

• Power

• Gas & fluids (connectors, gas regulation, breathing equipments)

• Transport (railway, automotive, off-highway, bicycle components)

Our production capacitiesWe are able to forge any kind of parts, from both small to large dimensions (>600mm) but also to develop components by forging two different types of material (simultaneous forging of different materials), always taking in consideration their compatibility criterion.

The bi-material finished part enables you to benefit of both combined alloys advantages, for example aluminium and brass or aluminium and steel.

Our forged parts are ideal for their lightness, resistance and precision.

Forged Alloy applications are in continuous development• Series1000: Mechanical parts with sulphuric anodizing, electrical, chemical and food components...

• Series 2000: Aeronautical and mechanical components (easy machining)

• Series 5000: Lamp and building components, carpentry...

• Series 6000: Automotive and nautical components / high corrosion resistance (easy forging)

• Series 7000: Sports, aeronautical and defence components / high hardness (easy machining)

Forged aluminium - The performance

Strength Some aluminium alloys approach or surpass the strength of commonly used steel.

Appearance

Visual appearance and high-performance as requested by designers and consumers.

Light weight

Aluminium weighs about 35% as compared to steel by volume.

Resilience

Aluminium alloys will deflect under load and spring back, providing flexible strength and shape retention.

Corrosion resistance

Aluminium doesn’t « rust away » on exposure to the environment like steel. Its natural oxide coating blocks further attack by oxidation. The risk of galvanic corrosion can be minimized by protective measures.

(

Joining

Aluminium can be joined by all common methods including: welding, crimping, folding…

Cold resistance

Aluminium has higher strength and ductility at subzero temperatures and is often used for cryogenic applications.

Thermal conductivity

Aluminium conducts heat about 1,8 times better than copper. It is an excellent material for heat exchangers, radiators, etc…

Recyclability

Recycling aluminium is economic (substantial scrap value) Aluminium has a well-established market for recycling. Recycling aluminium provides environmental benefits.

Savings Material savings on implementation and time savings on production, the forged part being very close geometrically to finished part, additional work/machining is limited.
