Green Aluminum Manufacturing
At CASS, we are transforming aluminum manufacturing with a focus on sustainability, innovation, and precision. As North America's only aluminum ingot manufacturer producing chlorine-free, flux-free, and chemical-free alloys we are setting a new standard in the industry-combining cutting-edge technology with environmentally responsible practices.
Whether you're a new visitor or a long-time partner, discover how CASS delivers exceptional aluminum solutions designed to meet your unique needs and elevate your operations.
What We Do
CASS manufactures 100% recycled aluminum alloys through a sustainable, innovative process that prioritizes:
100% Recycled: We transform recycled metals and post-consumer materials into high-quality aluminum ingots.
Custom Alloys: We tailor our aluminum alloys to meet your exact specifications, ensuring they perform in even the most demanding applications.
Industry-Leading Quality: Advanced lab technologies allow us to control elemental ranges, guaranteeing precision and consistency in every ingot.
Global Standards: As an LME-registered brand, we deliver products that exceed market requirements.

Chlorine is a highly toxic and corrosive gas, yet many secondary aluminum producers still use chlorine gas or chlorine-containing fluxes. Historically, chlorine has been associated with chemical warfare, posing significant risks. At CASS, we are committed to never taking such risks in our operations!
-
To reduce costs, many secondary aluminum producers choose nitrogen in their degassing process. To guarantee a superior product made in a safe and environmentally friendly way, CASS uses argon - a colorless, odorless, tasteless and non-toxic noble gas that can provide an inert & clean environment free of problematic elements.
-
We have chosen not to use fluxes in the removal of magnesium and the purification of molten aluminum from oxides and hydrogen. Instead we blend down the magnesium using higher purity material. This practice requires us to be more diligent but results in a secondary marketable product that is CHLORINE-FREE.
Clean & Safe Manufacturing
At CASS, we are committed to safety, quality, and sustainability. Unlike many secondary aluminum producers, we do not use chlorine gas or chlorine-containing fluxes due to their toxic and corrosive nature. To protect the environment and ensure superior products, we use argon instead of nitrogen in our degassing process, providing a non-toxic, clean environment. Additionally, we avoid fluxes for removing magnesium and purifying molten aluminum, opting instead for a more precise method using higher purity material, resulting in a cleaner, safer product.
Why CASS Stands Out
-
The Only Chlorine-Free Manufacturer in North America
Many aluminum producers use harmful chemicals like chlorine gas or fluxes, which can harm the environment and compromise product quality. At CASS, we’ve eliminated these practices, choosing safety and sustainability without sacrificing performance.
-
Advanced Automation & Technology
We are the only secondary aluminum manufacturer utilizing AI-driven molten metal management, which enhances safety, reduces risks, and ensures a superior product.
-
Sustainable Aluminum Production
Inspired by sustainable farming principles, we’ve created an “organic” aluminum production process that uses argon gas instead of nitrogen for clean, non-toxic degassing, avoids fluxes by blending magnesium with higher-purity materials, and results in products that are safer, cleaner, and better for the planet.
Quality and Efficiency in Aluminum Manufacturing
At CASS, we utilize advanced metal analysis technology to ensure the highest precision in our recycling and aluminum manufacturing processes. This state-of-the-art equipment allows us to meet customer specifications with exact elemental analysis, ensuring the production of chlorine-free, chemical-free alloys with exceptional accuracy. The technology provides fast, reliable results, enabling us to efficiently control the quality of both incoming materials and finished products. With reduced maintenance costs, minimal downtime, and increased reliability, we consistently deliver high-quality, environmentally responsible aluminum while optimizing our processes for maximum efficiency.
Low Carbon Aluminum: A Smarter, Greener Alternative
CASS is redefining aluminum manufacturing with Low-Carbon Aluminum, designed to reduce environmental impact without compromising quality. Using 100% recycled content, eliminating harmful chemicals, and leveraging energy-efficient processes, we provide a cleaner, more sustainable solution to support your business’s environmental goals. Our closed-loop system ensures the highest sustainability standards, offering businesses a competitive edge.
Lower Emissions: Our process significantly reduces greenhouse gas emissions compared to primary aluminum production, helping businesses meet sustainability goals and strengthen their environmental commitment.
Closed-Loop Recycling & Buyback Program: Our buyback program keeps aluminum in circulation, reducing the need for raw materials and supporting a closed-loop system that enhances efficiency and sustainability.
Meeting Global Standards: Produced with 100% recycled materials, our low-carbon aluminum helps businesses comply with stringent carbon regulations, including the Carbon Border Adjustment Mechanism, making it ideal for international markets.
Technical Expertise & Flexibility: Our team offers tailored alloys, sustainability guidance, and reliable partnerships to help you navigate regulations and achieve high-performance, environmentally responsible aluminum solutions.

Atomic Number 13
ALUMINUM, the element in which sustainability meets strength, symbolized by its atomic number 13. With an atomic weight of approximately 26.98 atomic mass units, this metal is known for its lightweight properties, having a low density of about 2.70 g/cm³. It has a melting point of around 660.32°C and a much higher boiling point of 2519°C. At room temperature, aluminum exists in a solid phase. It is an exceptional conductor of electricity—surpassed only by copper—and is similarly efficient in conducting heat, which makes it ideal for use in radiators and air conditioners. Notably resistant to corrosion, aluminum forms a protective oxide coating when exposed to air. This metal is both ductile, allowing it to be drawn into wire or extruded into shapes, and malleable, enabling it to be hammered or rolled into thin sheets. These properties make aluminum a versatile material in various industrial applications.
Benefits of Aluminum
-
Aluminum, like other metals, has atoms bonded together in a crystal structure, making it easy to melt and reform without losing its essential properties. This allows aluminum to be recycled indefinitely with no theoretical limit.
-
Manufacturing products from recycled aluminum saves up to 95 % of the energy needed to manufacture them from virgin materials.
-
Aluminum is a unique element of American manufacturing, supporting many segments of the U.S. economy.
Aluminum is designated as a critical mineral and has been recognized by the Departments of Commerce and Defense as “vital” to national security.
