Metal

What Are Lightweight Metals? A Beginner’s Guide

You often see lightweight metals in airplanes, cars, and even electronics. These metals have densities typically less than 3 g/cm³, which makes them much lighter than traditional materials. For example, an aluminum-based alloy can reach a density of only 2.4 g/cm³ while still achieving a high specific yield strength.

Galvanized vs. Galvannealed Steel

Galvanized vs. Galvannealed Steel: What’s the Difference?

When you compare Galvanized vs. Galvannealed Steel, you see clear differences in coating, appearance, and performance. Galvanized steel gives you a shiny finish and strong corrosion resistance, making it ideal for outdoor and structural uses. Galvannealed steel offers a matte surface, better paint adhesion, and improved weldability, which suits automotive and architectural projects.

Countersink Holes in CNC Machining

What Are Countersink Holes? A Guide for CNC Machining

A countersink creates a tapered recess in a material that allows a screw or bolt head to sit flush with or below a surface. Using precise dimensions, you can improve part quality and assembly efficiency. By understanding how to specify and create countersinks, you will be able to better control your CNC machining projects.
