CNC Machining of Corrosion-Resistant Materials
Build parts that last. We specialize in the precision machining of a wide range of metals and polymers designed to withstand the harshest chemical, marine, and biological environments, ensuring the long-term reliability of your components.
A Material for Every Corrosive Challenge
We offer a range of materials with inherent corrosion resistance, complemented by advanced surface finishes for ultimate protection.
Corrosion-Resistant Metals
Stainless Steel
The Industry Standard for Corrosion Resistance. Due to its chromium content, stainless steel naturally forms a passive, protective oxide layer.
Grade 316/316L: Offers superior resistance to chlorides (like salt water), making it the top choice for marine, medical, and food-processing applications.
Grade 304: Provides excellent general-purpose corrosion resistance for atmospheric and chemical exposure.
Titanium
Immune to Seawater and Body Fluids. Titanium and its alloys exhibit outstanding resistance to a wide range of acids, chlorides, and especially saltwater. Its excellent biocompatibility also makes it resistant to corrosion from bodily fluids.
Common Grade: Ti-6Al-4V (Grade 5).
Aluminum
Naturally Resistant & Enhanceable. Aluminum naturally forms a protective oxide layer. This resistance is dramatically enhanced through Anodizing, which creates a hard, ceramic-like surface that is extremely resistant to corrosion, wear, and fading.
Common Grades: 6061, 5052 (Excellent marine grade).
Brass & Copper
Good Resistance to Water and Brine. These alloys are known for their good resistance to corrosion from water, including salt water (brine), making them suitable for plumbing and marine hardware.
Corrosion-Resistant Polymers
PEEK (Polyether Ether Ketone)
Resistant to Nearly Everything. PEEK offers the broadest range of chemical resistance of any machinable polymer. It is inert to most common solvents, acids, and bases, even at high temperatures, making it ideal for chemical processing and oil & gas applications.
PTFE (Teflon)
The Most Chemically Inert Plastic. PTFE is virtually immune to all chemicals and solvents. It is the essential choice for high-purity fluid handling systems, chemical seals, and laboratory equipment.
PVC (Polyvinyl Chloride)
Excellent Acid and Alkali Resistance. PVC offers broad resistance to acids, alkalis, and many other inorganic chemicals, making it a cost-effective choice for chemical processing components and tanks.
Adding a Layer of Defense with Surface Finishes
For materials like aluminum and steel, we can apply specialized surface treatments to dramatically improve their corrosion resistance.
Anodizing (for Aluminum)
This electrochemical process is the best way to protect aluminum. It creates a hard, ceramic-like oxide layer that is much thicker and more durable than the natural oxide film, providing exceptional protection against salt spray and environmental corrosion.
Passivation (for Stainless Steel)
A chemical treatment that removes free iron from the surface and enhances the natural passive oxide layer, significantly improving corrosion resistance, especially in chloride-rich environments.
