Brass vs Bronze vs Copper

Brass vs Bronze vs Copper

The debate about brass vs bronze vs copper has been around for years. The apparent reason is that these metal titans make our lives possible in different ways. Life would be incomplete without any of those.    From households to industrial-level products, these metals play pivotal roles in maintaining lives. However, these three metals differ…

17-4 PH stainless steel material introduction

17-4PH Executive standard: American ASTMS17400, ASTM A564 630, UNS630 17-4PH is a martensitic precipitation hardening stainless steel. In addition to directly obtaining martensitic structure after solid solution treatment, this steel is further strengthened by subsequent aging treatment-obtaining precipitation hardening phase (copper-containing phase). 17-4PH is a precipitated, hardened, martensitic stainless steel composed of copper, niobium/columbium. This…

Is Aluminum A Common Prototyping Material?

CNC custom aluminum parts

Is Aluminum A Common Prototyping Material? If you’re a product designer, you’re probably wondering, “Is aluminum a common prototyping material?” If so, you’re not alone! Aluminum is often used for prototype manufacturing due to its outstanding qualities, including corrosion resistance and strength. This makes it a highly suitable choice for various projects, from pre-production prototypes…

Steel Material

CNC machining stainless steel

45 steel 45 steel is the name in GB, also called “oil steel”, this steel has higher strength and better machinability. Material advantages: It has high strength and good machinability. After proper heat treatment, a certain degree of toughness, plasticity and wear resistance can be obtained. The material source is convenient. It is suitable for…

Five difficulties of stainless steel processing products

1. When stainless steel is processed, the workpiece and the tool generate high heat, and the tool is easy to wear. Therefore, there are certain requirements for the knife, which must be wear-resistant and high-temperature resistant. At the same time, make the cutting edge sharp and choose a reasonable angle. 2. The speed is slow,…

Properties and application of PA material after adding fiber

In recent years, PP fiber reinforced materials have developed rapidly in the modified plastics industry, and most of the glass fiber reinforced materials used in the automotive field are PP substrates. With the improvement of plastic modification technology and the needs of the development of the automotive industry, the development trend of long glass fiber…
