Aluminum alloys
Lightweight housings, fixtures, heat-management parts and general machined components.
RFQ checksGrade and temper, anodizing response, cosmetic surfaces, distortion and conductivity.
Materials
Choose material from function, not familiarity.
Jinxi reviews grade, condition, stock form, geometry, finish, inspection and availability together. The groups below are sourcing starting points—not a promise that every grade, size or certification is in stock.
Material and finish planning
How should a buyer match material and surface finish?
Start with the functional requirement, environment and drawing specification, then confirm the exact material grade, condition and compatible finish before quotation. Strength, corrosion resistance, appearance, conductivity, wear, dimensional change and masking needs can all affect the process route. Jinxi reviews the material and finish as one manufacturing decision rather than treating them as separate checklist items.
Material definitionSpecify grade, temper or condition, certification need and approved substitutions.
Finish definitionSpecify appearance, functional requirement, controlled surfaces, masking and acceptance criteria.
Engineering confirmationAvailability, compatibility, dimensional allowance and inspection are confirmed per project.

Material groups
Common starting points for technical review
Exact grade, temper, hardness, source standard and documentation must appear on the RFQ or drawing.
Carbon & alloy steels
Loaded, wear-sensitive or heat-treated components and tooling.
RFQ checksGrade, condition, heat treatment, hardness depth, grinding allowance and corrosion protection.
Stainless steels
Corrosion-resistant, cleanable and appearance-sensitive components.
RFQ checksExact grade, magnetic/corrosion requirement, work hardening, passivation and surface condition.
Copper & brass alloys
Conductive parts, fluid components, inserts and decorative applications.
RFQ checksAlloy, conductivity, burr control, joining, plating and material identification.
Titanium & nickel alloys
High-performance parts where weight, heat or corrosion requirements justify the route.
RFQ checksGrade, traceability, tool access, heat generation, contamination control and project-specific capability.
Engineering plastics
Insulating, low-friction, low-weight or chemically resistant components.
RFQ checksResin grade, moisture/temperature, dimensional stability, stress relief and cosmetic acceptance.
