  1. Getting Your Expanded Metal Mesh Project Quoted: What You Need to Know

    Leave a Comment

    When working with a custom expanded metal mesh supplier, the company you choose should work closely with you to develop a custom product that suits your exact requirements and specifications. This checklist will guide you through the primary information to provide your supplier during the quoting process to ensure they can meet your needs and provide high-quality expanded metal mesh within your timeline.


    What to Have Ready for Your Supplier

    Before you request a quote from a prospective supplier, have a list of your project needs ready. You should provide information such as:

    • Type of Raw Material Alloy. There are various raw material alloys available, each offering its own unique properties and benefits. It is crucial to consider your application’s requirements for cost, corrosion resistance, density, hardness, yield strength, tensile strength, elongation, magnetism, bend rating, and more when choosing the right expanded metal material.
    • Raw Material Thickness. Years ago, metal foil could be expanded as thin as 50 microns and up to 36 inches in width. Today, metals can be expanded down to 30 microns and 40+ inches in width, with more advanced technologies capable of expanding metals even wider.
    • Coil Width. Creating expanded metal foil involves slitting and stretching a lightweight metal coil to produce a consistent mesh pattern of openings. 
    • Raw Expand Length. Expanded metal is an ideal solution for applications where weight is crucial due to its ability to be produced thinner than alternative open area materials.  Long coil lengths are only limited by raw material availability and finished coil weights.

    • Strand. Key measurements of expanded metal mesh include strand width (SW), short way of the diamond (SWD), and long way of the diamond (LWD).expanded metal mesh measurements
      • SW. This refers to the amount of material that should be slit from the parent material to form the opening.
      • SWD. This refers to the distance from one joint’s center to the adjacent joint’s center across the diamond’s short axis. 
      • LWD. This refers to the distance from one joint’s center to the adjacent joint’s center across the diamond’s long axis.
    • Leveling. If your project is working with leveled materials, you must provide the thickness of the leveled/flattened material (manufactured material thickness).

  2. How CThru Metals Helped Michigan’s Racing Team across the Finish Line

    MRacing — the University of Michigan’s Formula SAE team — is tasked each year with designing a formula-style race car to race against other college teams worldwide. This year, the design engineering team wanted to make sure their 36th vehicle was built for strength and speed to compete against fully electric race car competitions in both North America and Europe.

    Ranked 5th in the world out of 600 teams, the MRacing team had a reputation to uphold. They reached out to CThru Metals, hoping to leverage our expanded metal foil’s high strength-to-weight ratio to complete the vehicle’s design specifications, and our team was happy to help.

    The MRacing vehicle contains carbon fiber throughout its battery pack housing and monocoque chassis. By inserting expanded metal foil under the top ply of the car’s composite layups, the foil acted as a grounding layer across the surface of the carbon fiber parts. Because the car can become conductive, this expanded metal foil solution delivered the dual benefit of shielding the car’s high-voltage electronics in accordance with FSAE regulations, while also allowing the car to maintain top speed and performance.

    More on Expanded Metal Foil’s Benefits

    Expanded metal foil outperforms woven wire and perforated metals in conductivity, strength, stability and waste generation. More industries and applications are turning to expanded foil for these reasons — CThru’s foil is used in lightning strike protection for aircraft, wind turbine blades, and other carbon fiber uses for batteries, and fuel cells.

    Why should I use expanded metal foil for battery components or electric vehicle applications?

    Perforated metal and woven wire account for the two most common alternatives to expanded metal foil. However, expanded metal foil comes with a few key benefits that applications won’t see using either woven wire or perforated metals.

    Woven wire comprises several strands of material, while expanded metal foil consists of a single roll of material with precise, regular openings. The homogenous design of expanded metal foil allows for more consistent resistivity and conductivity. It also makes the material more suitable for applications that require accurately sized openings for optimal system or product performance.

    Expanded metals can also eliminate the yield limitations of perforated metals due to the lack of scrap produced throughout the manufacturing process. The elimination of waste is particularly crucial when working with high-value specialty or exotic metals. 

    Each of these advantages makes expanded metal foil ideal for a wide range of battery applications.

    How can I visit CThru at the show?

    If you would like to visit CThru at The Battery & Electric Vehicle Show 2021, contact us here so we can coordinate a meeting time at our booth to show you more. We look forward to seeing you at the event.
