Yes. We collaborate with clients to create custom alloys that meet targeted mechanical, thermal, or corrosion performance requirements — especially for advanced automotive or structural applications.
Aluminium Billets
Internal casthouse billets for extrusion performance — with external supply
At Ozbros Ltd, aluminium billet is a core internal material stream that supports our integrated manufacturing route—feeding our extrusion and flat-rolled programmes with controlled chemistry, consistent metallurgy and stable processing behaviour.
In addition to supporting our own production, we can also supply aluminium billets externally for customers who require reliable billet quality, defined alloys and consistent dimensions—subject to specification, volume and availability.
What our billet stream is designed to achieve
Because our billets are produced to support demanding downstream processes, the programme focuses on the factors that directly impact extrusion performance and total cost:
- Controlled chemistry to match alloy requirements and profile behaviour
- Stable metallurgical condition for repeatable press performance
- Consistent billet dimensions to support predictable processing
- Reduced variation between batches to improve downstream yield
- Traceability to support quality systems and industrial standards
Internal benefit: why billet quality matters for extrusion
Billet quality is one of the strongest drivers of extrusion outcomes—especially for structural and tight-tolerance profiles. High-quality billets help deliver:
- More stable extrusion behaviour and consistent surface quality
- Reduced scrap and fewer process interruptions
- Improved dimensional repeatability
- Better mechanical performance consistency (alloy/temper dependent)
- Improved die stability and reduced corrective actions (profile dependent)
This is exactly why billet production sits at the start of our integrated manufacturing route.
External supply:
While billets are primarily produced to serve internal demand, we can support external supply in two common ways:
- Planned supply from our production stream
Suitable for customers with consistent alloy and dimensional needs. - Dedicated billet campaigns
Suitable for customers needing specific alloys, verification requirements, or supply schedules.
If you want to buy billets, share your alloy, diameter, length and annual volume—plus any standard/testing requirements—and we’ll confirm feasibility and the best supply route.
Alloy range (typical programme)
We can support a broad alloy range, including:
- 1050, 1070
- 6060, 6061, 6063, 6082, 6463
- 7005, 7020
- Special customised alloys (subject to technical scope and volume)
We also work with customers on alloy selection and optimisation where there is a clear benefit to:
- Reduce processing cost
- Improve performance and consistency
- Support advanced structural applications
Billet dimensions
Diameters: 6″, 7″, 8″, 9″, 10″, 14″
Lengths: up to 7,300 mm
(If you’d like, we can add a short selection note here explaining how diameter choice typically links to press/container requirements—useful for buyers.)
Homogenisation approach (why it matters)
Homogenisation is a key thermal step that supports more consistent billet condition and extrusion behaviour. Ozbros uses a controlled homogenisation route designed to support:
- Uniform metallurgical condition across billet length
- Consistent extrusion response and reduced variability
- Improved repeatability across production batches
Exact cycles and routes are selected based on alloy and application requirements.
Quality control, verification and traceability
Billet quality control is built around consistent production discipline and documented traceability.
Depending on project requirements, our quality approach can include:
- Alloy and chemistry control during casting
- Process monitoring across key casting parameters
- Dimensional checks and identification marking
- Optional ultrasonic testing (ut/ndt) where the application demands internal verification (particularly relevant for structural, safety-related profiles)
We can align verification and documentation to customer quality systems and industry standards where applicable.
Automation & data-driven manufacturing control
Our billet stream supports modern manufacturing expectations through:
- Automated process control and monitoring
- Production data capture (MES-style workflows)
- ERP traceability (SAP-style workflows)
- Batch/heat/lot identification for controlled repeat supply
This enables practical benefits such as consistent repeat orders, faster issue resolution, and audit-friendly documentation.
Compliance & standards
We supply billets aligned to customer specifications and commonly used European and American standards frameworks where required.
If you have a defined standard, temper route, inspection plan or documentation format, include it with your RFQ.

Frequently Asked Questions
Producing billets within the same facility as extrusion operations ensures better alloy consistency, improved die performance, and enhanced mechanical strength in the final profiles. It also reduces logistics costs and lead times.
We supply a wide range of alloys including 1050, 6060, 6061, 6063, 6082, 7005, and 7020, as well as custom-developed alloys designed to meet specific application requirements.
Continuous homogenisation creates a more uniform grain structure and chemical consistency, which improves strength, ductility, and overall product stability compared to traditional batch homogenisation.
Our billets are produced with advanced hot-top air-slip casting technology and undergo ultrasonic non-destructive testing. This guarantees superior purity, dimensional accuracy, and defect-free results.
