New materials and surface treatments options for CNC milled parts
Expanding your options for greater flexibility and precision
meviy is expanding its portfolio of materials and surface treatments for CNC milled parts, giving engineers greater flexibility to choose the right combination for demanding applications. From high-performance tool steels to corrosion-resistant stainless steels, our updated lineup ensures components meet precise specifications while maintaining durability and manufacturability.
Now, alongside our existing metals, copper and brass grades are also available for automatic quotation, including EN CW004A Equiv., EN CW008A Equiv. (ETP), EN CW509L Equiv. (Brass), and EN CW614N Equiv.
Whether you are working in mold and tooling, electronics, or marine applications, these new materials and treatments enable parts to withstand challenging environments — including heat, chemicals, and seawater — while ensuring consistent quality from prototype to production.
What engineers struggle with
Engineers in tooling, electronics, and precision manufacturing often face limited material choice, corrosion issues, and slow quoting processes.
- Lack of hardened steels: key grades such as SK3, SKS, and DC53 were missing, forcing engineers to compromise or order elsewhere.
- Corrosion risks: stainless options like SUS304 were unsuitable for marine or chemical settings, leading to failures over time.
- Slow copper and brass quoting: conductive parts required manual quotations, delaying projects and breaking meviy’s instant-quote promise.
In short, engineers lost time and flexibility (waiting for quotes, adjusting designs, and managing multiple suppliers).
What this launch changes
This New Materials release removes these barriers by extending meviy’s material options and enabling automatic quotation for copper and brass.
- New tool steels (EN 1.1545, EN 1.2510, DC53®) provide superior hardness and wear resistance.
- New stainless steel (EN 1.4404 / SUS316L) offers exceptional corrosion protection in marine and chemical environments.
- Automatic Quotes for copper and brass (EN CW004A, CW008A, CW509L, CW614N) delivers instant quoting for conductive and decorative parts.
New tool steel options
Our tool steel range now includes the following materials:
- EN 1.1545 Equiv.

EN 1.2510 equivalent
EN 1.2510 equivalent is a high-performance tool steel designed for precision tooling and molding applications. Its strength and toughness make it suitable for components exposed to repeated stress. With meviy’s batch dimensioning and surface treatments, engineers can optimise EN 1.2510 equivalent parts for wear resistance, reduced friction, and long service life, particularly in electronics and tooling applications.
DC53® (Daido)
DC53® is a premium high-speed tool steel known for superior wear resistance and thermal stability. This material is perfect for precision molds and dies that require consistent performance under high temperatures. meviy supports all compatible surface treatments for DC53®, enabling engineers to achieve enhanced hardness, corrosion resistance, and long-lasting precision across the component lifecycle.
These high-performance steels can be paired with a range of surface treatments to enhance wear and corrosion resistance:
- Black oxide – increases corrosion resistance and reduces glare.
- Electroless nickel – offers a uniform coating ideal for complex geometries.
- Chrome plating (Flash) – provides high wear resistance and low friction.
- Nitriding – enhances surface hardness (available for tool steels only).
Heat treatment options for tool steels include:
- Conventional – standard thermal treatment for general applications.
- Vacuum – minimises distortion while increasing hardness.
This expansion directly responds to frequent requests from engineers and manufacturers for tool steels suitable for molds, dies, and high-wear components.
New Stainless steel option
To meet the demands of chemical and marine environments, meviy now offers:
EN 1.4404 equivalent
EN 1.4404 equivalent is a corrosion-resistant stainless steel ideal for components used in chemical, marine, and high-moisture environments. Its excellent rust and heat resistance make it perfect for seawater applications or parts exposed to harsh chemicals. Combined with meviy’s CNC milling capabilities, engineers can ensure durable, corrosion-proof, and high-precision parts without compromising manufacturability or delivery speed.
Size and delivery options
| Material type | Max size (AQ) | Max size (MQ) | Delivery |
