UHMW polyethylene (ultra-high molecular weight polyethylene) provides outstanding wear and impact resistance at low cost, used for conveyor guides, wear strips, and sliding contact surfaces. PEEK (polyether ether ketone) is a high-performance engineering plastic rated for continuous use at temperatures up to 480°F (250°C) with excellent chemical resistance, used in medical, aerospace, and semiconductor equipment. Nylon (PA6, PA66) machines easily and offers good wear resistance and moderate chemical resistance, used for bushings, spacers, and structural brackets.

For most structural brackets, enclosures, and robotic components, aluminum 6061-T6 is the best starting point — it is lightweight, strong enough for most applications, inexpensive, and machines quickly. If higher strength is required at the same weight, 7075-T6 aluminum is the upgrade path. For shafts and load-bearing cylindrical components, 4140 steel offers an excellent combination of strength and toughness at reasonable cost. If corrosion resistance is required, 303 or 316 stainless steel are the go-to choices depending on severity of the environment. For parts requiring low friction or self-lubrication, Delrin or UHMW are effective options. Olympus Machining can assist with material selection as part of the quoting and design-for-manufacturability (DFM) review process." } }, { "@type": "Question", "name": "What is the most common material for CNC machining?", "acceptedAnswer": { "@type": "Answer", "text": "Aluminum 6061-T6 is by far the most commonly CNC machined material across the industry, and it is also the most frequently machined material at Olympus Machining LLC. Its popularity stems from a combination of attributes that make it ideal for a wide range of machining applications: it has excellent machinability (cuts quickly with good surface finish, extending tool life), a favorable strength-to-weight ratio (much lighter than steel at comparable structural strength), good corrosion resistance suitable for most indoor and outdoor environments, and broad availability in standard bar, plate, and block stock sizes. Aluminum 6061-T6 is the default choice for robotics components, enclosures, brackets, spacers, structural frames, and prototypes across industries from consumer electronics to aerospace. When designers need a machined part and have no specific material requirement, 6061-T6 aluminum is almost always the first recommendation, offering the best combination of cost, performance, and machinability." } }, { "@type": "Question", "name": "Can Olympus Machining machine exotic or specialty metals?", "acceptedAnswer": { "@type": "Answer", "text": "Olympus Machining's primary focus is on the most common industrial and defense materials — aluminum alloys, carbon steels, alloy steels, stainless steels, and engineering plastics — which cover the vast majority of precision machining applications. For specialty or exotic metals such as titanium alloys (Ti-6Al-4V), Inconel (alloy 625, 718), Hastelloy, molybdenum, or tungsten, customers should contact Olympus Machining directly to discuss the specific application, quantities, and requirements. Exotic metals present unique machining challenges including high cutting forces, rapid tool wear, and stringent heat management requirements that affect tooling costs and cycle times. Whether a project involving exotic materials is a good fit depends on the specific alloy, part complexity, and quantities involved. Reach out to info@olympusmachining.com to discuss your specific material requirement and get a direct assessment of feasibility and lead time." } }, { "@type": "Question", "name": "Does Olympus Machining provide material selection guidance?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. Olympus Machining provides material selection guidance as part of its design-for-manufacturability (DFM) review process during prototype quoting. When customers submit a drawing without a specified material — or with a material that may be unnecessarily expensive, difficult to machine, or unsuitable for the application — the Olympus Machining team can offer practical recommendations based on engineering requirements and manufacturing cost. Common guidance includes substituting 303 stainless steel for 316 when chloride exposure is not a factor (reducing cost and improving machinability), switching from 4340 to 4140 steel when the maximum strength of 4340 is not required, or recommending Delrin over PEEK for room-temperature applications where PEEK’s high-temperature rating is unnecessary. Material recommendations are always framed in the context of the customer’s application requirements — strength, environment, weight, and budget — and the final decision always rests with the customer.

The right material choice directly affects dimensional tolerances, surface finish quality, mechanical properties, and overall manufacturability. Olympus Machining LLC is a [CNC machining shop](/) in Hanover, Pennsylvania that works with a range of metals and plastics to meet the functional and budgetary requirements of each project. As a dedicated machining vendor providing [precision CNC machining](/precision-cnc-machining) services, we apply material-specific tooling strategies and machining parameters to ensure optimal results for every material type. ## Aluminum Alloys Aluminum is one of the most commonly machined materials due to its favorable strength-to-weight ratio, excellent machinability, and corrosion resistance. We regularly machine aluminum alloys such as 6061-T6 and 7075-T6 for aerospace brackets, enclosures, heat sinks, and structural components. Aluminum machines efficiently at high speeds, allowing for tight tolerances and smooth surface finishes. It is well-suited for prototypes and production runs where weight reduction is a priority without sacrificing structural integrity. ## Carbon and Alloy Steels Carbon steels and alloy steels are selected for applications requiring high strength, hardness, and wear resistance. Common grades include 1018, 1045, 4140, and 4340. These materials are used in shafts, gears, fixtures, and industrial machinery components. Steel machining requires appropriate tooling, speeds, and feeds to achieve accurate dimensions and acceptable surface finishes. Heat treatment considerations are factored into machining sequences when hardened properties are specified. ## Stainless Steel Stainless steel grades such as 303, 304, and 316 are machined for applications where corrosion resistance, sanitary requirements, or elevated temperature performance is necessary. These materials are common in food processing equipment, medical devices, and marine hardware. Stainless steel is more challenging to machine than aluminum or mild steel due to its work-hardening characteristics. Proper tool selection and coolant application are essential to maintain dimensional accuracy and extend tool life. ## Plastics Engineering plastics such as Delrin (acetal), UHMW, nylon, and PEEK are machined for components requiring low friction, chemical resistance, or electrical insulation. Plastic parts are used in conveyor systems, bushings, wear pads, and specialized fixtures. Plastics require different machining parameters than metals to prevent melting, chipping, or poor surface finish. Tool geometry and feed rates are adjusted to accommodate the thermal and mechanical properties of each plastic type. ## Material Deep-Dive Guides Engineering comparisons and machinability guides for the materials we run most often.
