What Materials are Used in Broaching?

Broaching is a machining process that is used to cut metal or any hard material in an efficient manner. This versatile operation can be used for many types of cuts, from internal and external surfaces to splines, gears, and keyways. But the question remains – what materials are used in broaching?

In this article, we aim to answer this question by discussing the various types of materials which are commonly used in broaching operations. We’ll explore their properties, benefits, and other details so you can know what material best suits your needs! These materials are broached by different broaching machine by Taizhou Chengchun Automation Equipment Co., Ltd.

All in all, these are a few commonly used materials for broaching:


Brass is an often overlooked material when it comes to broaching. However, this metal has many advantages when it comes to the process of forming and shaping another material.

Brass is a malleable metal that gives off virtually no sparks or smolders during the broaching process. This makes it an ideal choice for jobs in safe or enclosed environments, as there is no need for nearby ventilation or additional fire safety measures.

Furthermore, brass’s combination of toughness and relative lightness — in comparison to iron — means that the pre-existing shape of embrittled material can be restored before further processing or machining operations are applied. When using brass for broaching, experienced professionals are able to produce remarkably precise sizes and shapes with consistent accuracy.


Aluminium is one of the best broaching materials due to its exceptional strength and lightweight. It’s used in a variety of industries, from automotive to aerospace because it can withstand high pressure and extreme temperatures. Its unique combination of low cost, ductility, recyclability, and corrosion resistance makes it an ideal choice for broaching.

The ability to precisely shape aluminum parts provides excellent performance that translates into higher levels of productivity. Additionally, its heat-treatable properties allow for increased strength and durability in parts machined with aluminum as the broaching material. All this means that aluminum is an effective and reliable solution for precision broaching operations.


The use of titanium as a broaching material is becoming increasingly popular due to its extremely lightweight properties. This material is particularly beneficial when small components, such as large-diameter bolts, need to be machined and threaded. Titanium doesn’t require large amounts of lubricant and maintains structural stability during the machining process.

Utilizing this intriguing metal for broaching provides the user with substantial absorption, durability, and wear resistance that is difficult to attain with other materials. It also has greater corrosion resistance, allowing for longer life of the cutting tool.

Overall, titanium is one of the best available materials for creating precise shapes in hard parts; allowing any business to save time and money on production costs.

Alloy steel

Alloy steel is an increasingly popular choice as a material for use in broaching processes. It is particularly notable for its combination of strength and ductility, making it one of the toughest materials available when metalworking.

Its physical properties mean that it can withstand high pressures without excessive wear, and its hardness ensures that won’t suffer from significant changes in dimensions over time.

Alloy steel also serves well to resist corrosion, making it ideal for use in environments where humidity or contact with other corrosive substances could be a problem.

Additionally, alloy steel is relatively inexpensive and easy to work with compared to other broaching materials, further boosting its popularity among engineers and industry professionals who are looking for an effective solution at a low cost.


Plastic is becoming increasingly popular as a broaching material due to its malleability, affordability and customizability. A process known as plastic injection molding allows complex shapes to be created quickly and easily, making it ideal for use in the construction of intricate parts like broaches.

Additionally, the surface of injection molded plastic products can be customized with textured finishes or colored particles, further increasing their versatility and appeal. Plastic’s low cost and versatility makes it an attractive alternative to other materials such as metal alloys.

As the demand for more efficient production methods increases, the use of plastic as a broaching material is likely to continue to grow.
