5 Key Benefits of CNC Machining
CNC machining, or computer numerical control machining, uses computer-guided equipment to cut metal and other materials with precision. These machines follow programmed instructions to produce detailed shapes and patterns. This process offers several important benefits that support accuracy, speed, and repeatability. Read more here.
Sinker EDM vs. Wire EDM: Key Differences and Applications
Electrical Discharge Machining (EDM) uses controlled electrical sparks to shape metal parts. It has two main types: Wire EDM and Sinker (Ram) EDM. Both remove material without direct contact but serve different purposes. This resource explains the key differences between Wire EDM and Sinker EDM. It will help you choose the right method for your specific machining needs. Read more here.
Everything You Need to Know About Sinker EDM Machining
Sinker EDM is a subtractive manufacturing process that removes material using electrical discharges. It uses a custom-shaped electrode that is lowered into a conductive workpiece while both are submerged in dielectric fluid. The electrode never touches the material. Instead, controlled sparks erode the surface to form precise cavities. Read more here.
Everything You Need to Know About Wire EDM Machining
Wire electrical discharge machining, more commonly known as wire EDM, is a specialized machining process that uses a thin, electrically charged wire and dielectric fluid to cut conductive materials to specifications. Read more here.
What is Inconel? Composition, Properties, and Uses
Inconel® is a family of nickel-based superalloys designed to perform in extreme heat, pressure, and corrosion. These alloys are made primarily from nickel and chromium, along with iron and other metals like molybdenum, niobium, and copper – depending on the specific grade. Read more here.
Monel vs. Inconel: What Are the Differences?
Inconel® and Monel® are two families of nickel-based alloys engineered for strength, corrosion resistance, and performance in demanding environments. While both are built on a nickel foundation, their alloying elements and mechanical properties set them apart. Read more here.
Is Inconel Magnetic
Engineers working with high temperature alloys often ask, is Inconel magnetic? The accurate answer is that most common Inconel grades are essentially nonmagnetic in their fully annealed condition, but they can become slightly magnetic after heavy cold work, forming, or welding. Read more here.
Is Brass Harder Than Aluminum
When engineers and buyers compare materials for precision CNC parts, a common question is, is brass harder than aluminum? The short answer is that most common free machining brasses are harder than the aluminum alloys typically used for CNC machining. The long answer is more nuanced and depends on alloy selection, part geometry, and performance requirements. Read more here.
Is Brass Stronger Than Steel
When engineers compare materials for precision CNC parts, a common question is, is brass stronger than steel? In most cases the answer is no. Typical carbon and alloy steels have higher yield strength and tensile strength than common brass alloys. That said, brass offers other advantages like machinability, corrosion resistance, and electrical conductivity that can make it the better choice for certain parts. Read more here.
