42CrMo4, also known as EN 1.7225, is a chromium-molybdenum alloy engineering steel selected when a machined part must combine high strength, fatigue resistance, toughness, and wear resistance. This guide is written for engineers, buyers, CNC machining teams, and product developers who need more than a simple datasheet. It explains what the grade means, how it […]

C45 steel is a medium-carbon engineering steel used when a machined component needs better strength and wear resistance than mild steel, while still remaining more economical and easier to source than many alloy steels. This guide explains C45 composition, equivalents, heat treatment, CNC machining behavior, surface finishing, application limits, and practical selection rules for custom […]

A practical, SEO-focused guide to S235 steel properties, variants, CNC machining behavior, surface finishing, applications, and buying specifications. What Is S235 Steel? S235 steel is a European non-alloy structural steel specified mainly for general load-bearing work, welded fabrications, machine frames, brackets, base plates, fixtures, and many custom CNC machined components. The name is practical: “S” […]

S355 steel is a high-strength structural steel widely used in construction, heavy equipment, transportation, and CNC machining industries. Known for its excellent weldability, toughness, and mechanical strength, S355 provides a reliable balance between durability and machinability. Different grades such as S355JR and S355J2 are selected based on impact resistance and operating conditions. What Is S355 […]

Tool steel is a family of high-performance carbon and alloy steels designed for wear resistance, edge retention, compressive strength, and controlled hardness after heat treatment. For CNC machining buyers, the important question is not simply which grade is the hardest. A better question is which grade gives the right balance of machinability, toughness, heat resistance, […]

Alloy steel is one of the most practical material families for engineered components because it lets designers tune strength, toughness, wear resistance, hardenability, and service life beyond what plain carbon steel can normally provide. This guide explains alloy steel from a manufacturing perspective: what it is, how common alloying elements work, how it compares with […]

EN 1.4301 stainless steel is one of the most widely specified austenitic stainless steels for CNC machining, fabrication, food equipment, architectural components, and general industrial use. This article explains the grade from a practical manufacturing perspective: what it is, how it performs, when it should be selected, and how to avoid common CNC machining problems […]

Brown anodized aluminum is widely used when a CNC machined aluminum part needs both functional protection and a warmer visual appearance. Unlike raw aluminum, it has an anodized oxide layer that improves corrosion resistance, surface hardness, and wear performance, while the brown or bronze tone gives the part a more refined, architectural, or consumer-product look. […]

Choosing between steel and galvanized steel is not only a question of strength. For CNC machining projects, the real decision usually depends on where the part will be used, how much corrosion resistance is required, whether the machined surface will be exposed, and what post-processing is planned after cutting. Plain steel offers strong mechanical performance, […]

Red bronze is a copper-rich alloy that is often discussed together with red brass and leaded bronze because these materials share a reddish appearance, good machinability, and reliable performance in wet or friction-heavy environments. For CNC machining buyers, the real value of red bronze is not only its color, but also its balance of corrosion […]

Bronze is generally not magnetic, but the answer becomes more useful when it is connected to alloy chemistry, CNC machining behavior, and real-world part identification. Many buyers ask this question because they are checking an unknown metal, replacing an old bushing, comparing bronze vs brass, or designing a component that must operate near magnets, motors, […]
