## What is Material Select｜Material Guide?

Enter a use such as "mold, wear priority" to organize candidates from 236 materials and the conditions to check next.

When a drawing needs a material callout or the service environment changes, it is easy to research candidates, standards, and manufacturing methods separately. Material Select keeps the work from discovery and comparison through cost estimates and saved project notes in one app.

■ Find candidates from a use
Supports 13 categories and 27 environments, including aircraft, space, seawater, molds, and electrical insulation. Search 236 metals, polymers, ceramics, composites, and more by name, alias, standard, or use. Reference candidates remain available without every condition entered; strict results distinguish an unsuitable material from missing data.

■ Compare standards and processing
Switch between JIS and US ASTM, SAE, AISI, UNS, and AA designations. Compare properties, machinability, and sources for up to three materials. Filter 22 surface-treatment processes by substrate, purpose, dimensional effect, and process temperature.

■ Keep the basis and cost of a study
Estimate per-part total cost with material, machining, treatment, and inspection costs kept separate. Save and restore conditions and candidates as project revision history. Reference weight calculations from volume, rectangular stock, or round stock, favorites, and SI/US unit switching are included.

【How to use】
1. Search by use or material name
2. Compare standards, properties, and machinability
3. Save the source material to check and the project study

【Purchase and data】
One app purchase unlocks all features. There are no in-app purchases, subscriptions, ads, or account registration. Material data and projects stay on the device. An external browser opens only when you tap a price-search or primary-source link.

【Reference information for material studies】
The app distinguishes 14 materials with detailed properties from materials indexed mainly by name and use. Representative values, relative machining indices, candidates, and calculations do not guarantee design approval or standards compliance. JIS and US standards are not necessarily fully interchangeable. For final design, confirm current standards, material certificates, product form, and actual service conditions with a qualified professional. The app does not automatically verify the authenticity or currency of supplied documents.
