Graphite for EDM is a unique material utilized in several industries known for its incredible thermal conductivity, strength, and resistance to wear. EDM graphite electrodes have become a staple for high precision applications that are able to produce high quality surface finishes.
Types of EDM Graphite
At the core of MWI’s EDM Graphite offerings is our signature Electro Carb “EC” Graphite. There is an EC grade available for every application. Here are a few of the most common:
- EC-12 is a general-purpose grade good for roughing while providing good finish and detail.
- EC-15 is a high-density graphite that provides increased electrode life, better surface finishes, and has an excellent flexural strength, making it perfect for difficult shapes and intricate details.
- EC-16 is a graphite grade with an ultra-fine grain that has thermal stability and wear resistance. It’s ideal for thin-rib electrodes, and fine detail. EC-16 is an excellent choice where corner detail needs to be maintained.
MWI also offers the exclusive HK graphite. Our HK material comes in HK-6 and HK-6C and is a perfect option for when super fine surface finishes are required. HK-6 and HK-6C graphite offer minimal electrode wear which means less electrodes are required to burn.
All graphite materials from MWI are high quality and competitively priced. Looking to learn more about what grade of EDM graphite is right for you? Contact us today and we will be happy to assist you.
Different Grades of Graphite
Different grades of graphite bring a range of valuable properties when used as EDM electrodes. These varying grades can influence the overall burn ratio, surface finish, and intricacy of the design details in the final product.
The higher the grade of graphite, such as EC-16, the greater the thermal stability and wear resistance. This makes it an excellent choice when high precision and durability are required. It can withstand complex shapes and intricate designs.
Mid-range graphite grades, like EC-14 or EC-15, offer a balance of density, strength, and cost, making them a versatile choice for a wide array of applications. They present a cost-effective solution while providing constantly high EDM performance.
Lower grades, such as EC-12, are designed for roughing applications and faster metal removal rates. This grade of graphite is particularly advantageous when cost or speed is a priority in the machining process.
