Gravity Die Casting Foundry for Aluminium Bronze Components
Gravity die casting has been the historical core business of Fonderie Davergne since 1947. Our foundry specializes in the production of technical aluminium bronze components, exclusively based on our three alloy grades: CuAl9, CuAl10Fe2 and CuAl10Fe5Ni5. This process allows us to manufacture robust, repeatable and reliable parts designed for demanding industrial environments.
Our Specialty: Aluminium Bronze Gravity Die Casting
Gravity die casting consists of pouring molten metal into a permanent metallic die using gravity alone. At Davergne, this expertise is entirely dedicated to aluminium bronze. We do not work with conventional aluminium: our know-how is focused on mastering three aluminium bronze grades designed for demanding mechanical, industrial and environmental applications.
Gravity die casting also avoids contamination and inclusions commonly associated with sand casting. The use of a permanent metallic die ensures better alloy control, more stable production quality and cleaner metallurgical properties, while eliminating waste generated by disposable sand moulds.
What makes us different: a strong specialization, a fully mastered process, experience gained through nearly 3000 developed references, and an in-depth understanding of aluminium bronze behavior in gravity die casting. From feasibility studies to fully machined finished components, we support projects requiring reliable, durable and repeatable parts.
The three main design rules for healthy gravity die cast components are: radii, draft angles and constant wall thicknesses.
These fundamental principles help guarantee proper metal flow, controlled solidification, easy demoulding and stable, defect-free castings.
Our three reference alloys are CuAl9, CuAl10Fe2 and CuAl10Fe5Ni5. This deliberate choice allows us to focus our expertise on high-performance alloys recognized for their mechanical strength, wear resistance and reliability in severe operating conditions.
At Davergne, we believe in a human-sized and responsive approach. Every project is handled directly by a dedicated team capable of quickly managing technical constraints, adjustments and unforeseen developments during production.
Our integrated machining workshop also allows us to fully control tooling manufacturing without relying on external subcontractors. This reduces lead times, limits technical back-and-forth and improves responsiveness throughout the entire project.
This integration also provides a major advantage for finished parts: machining operations can be carried out internally, exclusively for our foundry production. This avoids the common transfer of responsibility between external machine shops and foundries.
Quality control, technical consistency and final adjustments all remain centralized through a single point of contact.
Key Features
Simple benchmarks to understand the advantages of aluminium bronze gravity die casting.
Controlled Alloys
A deliberate specialization focused on our three aluminium bronze grades.
Repeatability
The metallic die ensures stable and consistent production from batch to batch.
Technical Components
A process designed for mechanically demanding and high-performance applications.
Resistance in Severe Environments
Aluminium bronze is recognized for its excellent wear and corrosion resistance.
Manufacturing Process
In short: technical study, die preparation, aluminium bronze melting, gravity casting, finishing and inspection.
Technical Study
Based on your drawings, 3D files or existing parts, we assess feasibility and adapt the design to gravity die casting requirements: shrinkage allowance, gating, venting...
Result: a part optimized for foundry production.
Die Manufacturing
The mould, also called a metallic die, is made from highly heat-resistant steel. It is machined and inspected so it can be prepared for stable and repeatable casting conditions.
Result: tooling ready for production.
Alloy Melting
The selected aluminium bronze grade is prepared and melted at 1200°C according to the metallurgical requirements of the project. Each melt is checked using spark spectrometry, tensile testing and hardness testing.
Result: controlled metal before casting.
Gravity Casting
The molten metal is poured into the die. Filling is carried out manually by gravity, without external pressure.
Result: a raw aluminium bronze casting.
Finishing & Inspection
After demoulding, the part is separated, deburred, machined according to customer requirements and then inspected.
Result: a compliant part, ready for use.
