Toughness is a mechanical property that measures the amount of energy a material can withstand, or absorb, before fracturing. In the context of other mechanical properties, toughness for steel products represents a balance of strength and ductility. As a material term, toughness can sometimes cause confusion: two very different materials can both be considered tough. […]
The heat treatment known as annealing encompasses a group of processing heat treatments. Unlike thermal processes that are used to improve the strength and wear resistance of a part (such as hardening heat treatments), processing heat treatments are used to prepare a workpiece for further manufacturing processes. Chiefly, this means improving a material’s responsiveness to […]
Imagine a medieval blacksmith hammering a sword fresh out of the fire. With the weapon still red-hot, he dunks it in water. The water hisses and boils around the submerged steel as it turns color from glowing orange to grey. This iconic scene of rapidly cooling a workpiece is called quenching, or quench hardening, and […]
Internal stresses form naturally during many manufacturing processes. Machining, stamping and welding, for example, are common manufacturing methods that augment the amount of stress in a material’s fabric. And although stress build-up is a natural byproduct of these processes, too much of it leads very commonly to part distortion. Most of these stresses must therefore […]
Joining multiple metal parts together into a single, cohesive unit is an indispensable process to manufacturing. Bolts, screws, and adhesives are often used to unite separate parts, but many applications call for a more solid connection. Thanks to the craft of welding, manufacturers are able to effectively create a single part from multiple components. Casting […]
Hardening a metal achieves much more than simply making it mechanically harder. It also improves strength, making the alloy more resistant to plastic deformation, and can aid with corrosion resistance. However, a harder metal is also often a more brittle metal. As such, hardening is usually just one part of a properly designed heat treatment […]
Normalizing is one of the most common heat treatments used in manufacturing carbon steel. It is a vital process to ensure that the mechanical and physical properties of a carbon steel workpiece are integrated and distributed uniformly across the material. In steelmaking, material uniformity is achieved by carefully controlling a casting’s microstructure — specifically, its […]
The Eagle Group is a team of manufacturing companies based in Muskegon, MI, made up of three foundries and a machine shop. Eagle Alloy, Eagle Aluminum, Eagle Precision and Eagle CNC are connected through common ownership and through common goals: while each company occupies its own niche, they often work together to provide “concept to […]
When a star jet pilot had a missing fuel cap at the Muskegon Air Show, the Eagle Group stepped in to replicate the part in less than 48 hours. Wings Over Muskegon took place in July, 2023 at the Muskegon County Airport. This interactive aviation experience was a revamped version of the Muskegon Air Fair, […]
When time and flexibility are top priorities, rapid prototyping for castings offers manufacturers a fast-track route to producing complex cast parts in small quantities. At
Eagle CNC’s West Michigan machine shop provides some of the highest-precision machining available, but the meaning of precision in machining is constantly changing. Industries across the board
ESOP is a way to transfer company ownership from one generation to the next—in many cases, this transfer happens when the original owners sell their stake
Recently, Eagle Alloy squared off against the demanding technical requirements and thorough audits of the American Bureau of Shipping’s “Type Approval” certification. Through this process,
