Tensile Strength<\/strong><\/h3>\nTensile strength is the ability of a material to withstand a pulling or stretching force. It is one of the most critical properties to consider when choosing a material, as it directly impacts the material\u2019s ability to resist deformation under tension.<\/p>\n
In CNC machining, high tensile strength metals like stainless steel (SS 304 or 316) are often used for parts that need to bear heavy loads, while in 3D printing, materials like titanium alloys and tool steels offer similar capabilities with the added benefit of complex geometries.<\/p>\n
Yield Strength<\/strong><\/h3>\nYield strength is the point at which a material begins to deform permanently<\/strong>. For both CNC and 3D printing, it is essential to choose a material that can withstand the forces it will encounter without yielding under operational stress (Check out our guide: Yield Strength of Steel: A Comprehensive Guide<\/a>).<\/p>\nFor high-performance applications, like aerospace or automotive parts, metals with high yield strength\u2014such as Inconel<\/strong> or maraging steel<\/strong>\u2014are commonly used.<\/p>\nHardness<\/strong><\/h3>\nHardness refers to a material\u2019s resistance to surface deformation, scratching, or indentation. Metals like hardened tool steels<\/strong> or titanium alloys<\/strong> are known for their superior hardness, making them ideal for applications requiring wear resistance or the ability to handle abrasive environments.<\/p>\nHardness can vary significantly in both CNC machining and 3D printing depending on the metal\u2019s composition and heat treatment processes.<\/p>\n
Fatigue Strength<\/strong><\/h3>\nFatigue strength is the ability of a material to withstand cyclic loading without failing. This is particularly important for parts that will experience repeated stress<\/strong>, such as in engine components or aerospace applications.<\/p>\nMetals such as aluminum alloys (e.g., 7075) and titanium alloys are prized for their high fatigue strength, making them suitable for industries where parts are subject to continuous loading and unloading.<\/p>\n
Impact Strength<\/strong><\/h3>\nImpact strength, or toughness, measures a material\u2019s ability to resist sudden forces or shock loads<\/strong>. Materials that can absorb energy without fracturing are crucial in applications like automotive crash zones or industrial equipment.<\/p>\nIn CNC machining, steel grades such as AISI 4140 are commonly used for their excellent impact resistance, while 3D printed metal parts made from materials like stainless steel or aluminum can also deliver high impact strength with optimized geometries.<\/p>\n
Elongation<\/strong><\/h3>\nElongation is the ability of a material to stretch before breaking. This property is essential for applications where flexibility or the ability to deform under stress is needed without failure.<\/p>\n
For both CNC and 3D printing, metals with higher elongation, such as aluminum<\/strong> or certain stainless steels<\/strong>, can be more desirable when flexibility is required, such as in the creation of brackets or structural components.<\/p>\nMetal Strength Chart<\/h2>\n
