Applications made possible by using Expanded Metal

By: admin September 10th, 2013

In 2009, three researchers, Dimas Smith from the Universidad Francisco de Miranda, Carlos Graciano and Gabriela Martinez from the Universidad Simon Bolivar published a paper that discuss the use of expanded metal in engineering applications. While some of the applications discussed were widely known, we appreciated the fact that the paper highlighted the advancements made by the use of expanded metal in applications from several different market sectors.

Given the high demand for Rare Earth Metals in modern technology. If the alloy developed from these metals is ductile, and the application allows for an open area configuration. In theory expanding the Rare Earth Metal alloy, may be more cost-effective in the development of the technology application . Enjoy the infographic below on Rare Earth Elements designed by the folks at the Visual Capitalist.

What effect does tarnish on copper have on product parameters?

By: admin March 22nd, 2012

This is one of the more common questions that we are asked. Customers are primarily concerned with adhesion and surface resistance. Does the surface resistance increase with increased tarnish levels? Will epoxy adhere to a tarnished copper surface? To try and provide an answer, we undertook some elementary evaluations of copper samples with varying levels of tarnish identified using the L*a*b* color space coordinates. For those unfamiliar with the L*a*b* system, the short answer is that every color can be defined in terms of 3 numbers. The first number, “L”, is for lightness which ranges from 0-100, with 0 being black and 100 being white. Everything else is shades of gray. The second number, “a”, is either positive (Red) or negative (green). The third number, “b”, is either positive (yellow) or negative (blue). That is it in a nutshell. All shades of copper and its tarnish can be defined in this way.
