Start with the material on your drawing.KingTeam provides custom parts in aluminium, stainless steel, carbon and alloy steel, brass, copper and bronze. Send the material specification with your drawing so we can review the grade, stock form and manufacturing route.The grades below are common examples. Availability, material condition and suitability for your part are confirmed during enquiry.Email your drawingsContact KingTeamAI-generated illustration: examples of metal stock for custom parts.
Common materials, grouped by family
Specify the alloy grade, product standard and material condition together. Include any restrictions on substitution.
Aluminium alloysCommon grades: 5052, 6061, 6082, 7075Examples for housings, brackets and plates. Specify the temper; review sheet-forming and anodising requirements with the selected alloy.
Stainless steelCommon grades: 303, 304, 316L, 17-4 PHExamples for shafts, fittings and housings. State the service environment, grade and condition; include passivation or other finishing requirements.
Carbon steelCommon grades: 1018, 1045Examples for pins, shafts and general mechanical parts. Confirm hardness, heat treatment and the protection needed for storage or use.
Alloy steelCommon grades: 4140, 4340Examples for loaded shafts and mechanical components. Specify the required heat-treatment condition and which dimensions apply afterwards.
BrassCommon grades: C36000, C26000Examples for turned fittings and formed components. Select the grade for the production route and state any lead-content restrictions.
CopperCommon grades: C11000, C10200Examples for contacts and heat-transfer components. Identify the required grade and conductivity requirements; colour alone cannot identify the material.
BronzeCommon grades: C93200, C51000Examples for bushings and other wear components. Specify the alloy and stock form; different bronzes need different manufacturing routes.
Special materialsOn enquiry: titanium, POM, PEEK and other specified materialsTitanium alloys, engineering plastics and unlisted grades can be discussed separately. Send the specification and part requirements for a feasibility review.
Confirm the specification before ordering
Agree the grade, condition and documents needed before material is ordered. Resolve any proposed substitution before purchase.
Grade and substitutionsKeep the drawing designation and product standard together. A proposed alternative needs comparison and your approval before use.Supply and final conditionState temper, hardness or heat treatment where required. Distinguish the incoming condition from the condition needed in the finished part.Material recordsTell us which certificates, batch references or additional checks you need. The document scope is agreed with the quotation.
Match the material to the production route
Include the operations that affect your choice of stock and material condition. A grade suitable for one route may need a different condition for another.
MachiningReview the stock shape and allowance with the finished geometry, including any thin walls or critical surfaces.Forming and forgingInclude the starting thickness or blank requirements where specified. Formability and the production route are reviewed for the actual design.Heat treatment and finishingSpecify the final material condition and surface treatment. Review their sequence with the dimensions required at delivery.Special restrictionsState any composition limits, customer specifications or restricted-substance requirements. Agree the supporting evidence before ordering.

Frequently asked questions
Practical details when specifying materials for custom parts.
Are all listed grades held in stock?The list gives common material examples. Stock availability, minimum purchase quantities and lead time are checked for each enquiry.Can you use an EN, ASTM, UNS or GB grade?Send the exact designation and product standard. We review the requirement as written and discuss any alternative with you.Are grades from different standards interchangeable?A similar name does not establish equivalence. Composition, properties, condition and product requirements need review before a substitution is approved.Can you provide material certificates?Specify the document type and traceability requirements in the enquiry. We confirm the available records and any additional checks before ordering.Can I request a material that is not listed?Yes. Send the grade, specification, drawing and quantity. Special alloys and engineering plastics are assessed separately.What if the material has not been selected?Tell us about loads, environment, appearance and other functional requirements. We can discuss manufacturing options; you approve the material specification for the application.
