Aluminum Alloys
State grade and temper, appearance zones and anodizing needs.
MATERIALS
Material decisions begin with the exact grade.
We review material family, grade, condition, stock form, geometry, finish and evidence requirements together. Availability and process suitability are confirmed at RFQ stage.
Review My Material
RFQ CATEGORIES
Common material families we can review.
These material families are common starting points for RFQ review. Grade, temper, hardness, stock size and certificate availability are confirmed for each order.
Carbon & Alloy Steels
State grade, delivery condition, heat treatment and hardness.
Stainless Steels
State grade, corrosion context and passivation or finish needs.
Copper & Brass
State alloy, conductivity relevance and cosmetic requirements.
Engineering Plastics
State resin grade, color, stability and service conditions.
WHAT TO SPECIFY
A usable material callout prevents rework.
If a standard permits multiple grades or conditions, identify which alternatives are acceptable before quotation.
Include ASTM, EN, DIN, JIS, GB or customer material designation.
Temper, annealed state, pre-hard condition or required final hardness.
State whether a CoC, mill certificate or batch traceability is required.
Define heat treatment, coating, plating, anodizing, passivation or black oxide.
Identify dimensions affected by heat treatment or surface build-up.
Mark cosmetic surfaces, color limits, masking and acceptable variation.
MATERIAL + FINISH REVIEW
Surface treatment is part of the tolerance plan.
Complementary surface treatments can be coordinated locally or through qualified partners. The treatment specification, dimensional allowance and inspection requirements must be defined before quotation and production planning.
| RFQ topic | Why it matters | Useful input |
|---|---|---|
| Coating build-up | Can change fits, threads, bores and datum relationships | Thickness range, masked areas and post-process measurement plan |
| Heat treatment | Can change distortion, stock allowance and grinding sequence | Hardness range, case depth, condition and certificate need |
| Cosmetic finish | Needs a visual standard rather than subjective wording | Color reference, grain direction, protected faces and sample approval |
| Material substitution | Can change strength, corrosion, machining and compliance | Written list of acceptable alternatives or no-substitution instruction |
FAQ
Material questions before quotation.
Can you recommend a cheaper substitute?
We can suggest commonly available alternatives for discussion. Production uses the material grade approved in the final RFQ.
Can material certificates be supplied?
Yes. State the certificate and traceability requirement in the RFQ so it can be included in material sourcing and quotation.
Can you coordinate heat treatment and surface treatment?
Yes, for accepted parts through a reviewed complementary process route. Specification, allowances, masking, certificates, appearance criteria and post-process inspection must be agreed where relevant.
