Shanghai Autra Precision Surface Treatment Co., Ltd.

TDS / SDS request

Enter the product or process name, and choose document type and language; available versions need to be checked.

Review the requirement summary first, then submit it for engineering review. This page does not generate quotes, lead times or technical guarantees online; for confidential material we can sign an NDA first.

Choose evaluation depth

1 · Substrate

Special metals and non-metals require separate confirmation of pretreatment, adhesion and applicable conditions.

1 · Product or process

2 · Main requirements & issues

Multiple choices allowed. For a quick evaluation, just select targets; for an in-depth evaluation you can enter values and test conditions.

Reference from existing processing data: 1–100 μm; the specific range is evaluated per workpiece.

Quick fill (customer target, not a capability commitment):
Conditions for applying the reference data

Existing processing data lists 1–100 μm, and some product documents state that more than 80 μm is possible. Applicable ranges differ by coating type, substrate and structure; these are not uniform minimum or maximum values. Please enter your drawing requirement or let an engineer recommend one.

Data include a record of 1000 h neutral salt spray for a specific process.

Quick fill (customer target, not a capability commitment):
Conditions for applying the reference data

1000 h is limited to a specific process and thickness; substrate, test standard, thickness, heat treatment and pass criteria must be confirmed in writing. The 100 h in the technical details is a historical comparison test, not a capability limit, and cannot be converted into service life.

A specific composite coating: HV550–600 as-plated; HV1000–1200 after heat treatment.

Quick fill (customer target, not a capability commitment):
Conditions for applying the reference data

This record applies to a SiC composite coating with 300°C heat treatment; holding time, test load, etc. need confirmation, and it does not represent all processes. Hardness is not wear life; please state separately whether the substrate allows heat treatment.

View technical data ↗

Evaluated by friction mode and actual mating; there is no uniform life limit.

Conditions for applying the reference data

Describe repeated sliding, abrasive wear or other wear modes, plus the mating material, load, speed and lubrication. The historical wear curves available are incomplete, so no unverified quantitative life ranking is given.

Distinguish dry friction, oil-lubricated or other lubrication environments.

Conditions for applying the reference data

The coefficient of friction depends on the counterpart, load, speed and environment; results from different tests cannot be combined into general upper and lower limits. If you have a friction coefficient target, please provide the test conditions as well.

Industry reference: typical resistivity of electroless nickel is about 30–100 μΩ·cm.

Conditions for applying the reference data

Data come from Nickel Institute technical documents and are not an AUTRA processing guarantee. Resistivity varies with coating composition and heat treatment; a workpiece's contact resistance and a material's resistivity are different metrics and must be tested under the actual contact condition.

View technical data ↗

Surface hydrophobicity is evaluated by metrics such as contact angle.

Conditions for applying the reference data

Contact angle must state the liquid, temperature, droplet volume and time of measurement. Surface hydrophobicity does not equal waterproofing or sealing of the whole part; actual wear, thickness and cleaning conditions should also be considered.

View technical data ↗

Evaluated based on the contact material, operating temperature and cleaning method.

Conditions for applying the reference data

Please describe the resin, adhesive or other contact substance, as well as the current sticking problem, operating temperature and target life. Food-contact or similar requirements need separate confirmation of the corresponding compliance documents.

View technical data ↗

Magnetism, low reflection, temperature resistance or special media can be discussed separately.

Conditions for applying the reference data

Please describe the use case and acceptance requirements as fully as possible. There may be trade-offs between multiple goals; please mark which must be met and which you hope to improve.
