Engagement Process

From handshake to sign-off — every step documented.

Four phases. Four deliverables. Zero ambiguity about what you're paying for or what you'll receive.

Phase 01

Audit

01

Inventory & Failure Review

We map your current alloy inventory against actual failure history. Every stress crack, every rejected batch, every scrap event gets logged against the spec that caused it.

Alloy Failure Map

Deliverable: Alloy Failure Map — a documented matrix of your alloy series, tempers in use, and associated failure modes over 24 months of production data.

Phase 02

Grade-Temper-Supplier Matrix

We produce a prioritized recommendation matrix: the right alloy, the right temper designation, and a ranked shortlist of qualified suppliers — with the reasoning documented for your procurement records.

Mill Negotiation & Cert Verification

We sit across the table from the mill on your behalf. We read the MTRs, verify the chemistry against the callout, and flag anything that would fail incoming inspection before it ships.

Mechanical Testing & Sign-Off

We don't close an engagement until the material proves out. We specify the test protocol, witness or review the tensile, hardness, and corrosion data, and issue a written sign-off tied to your part number.

We were running 6061-T6 on a weld-intensive bracket assembly and couldn't understand the HAZ failures. Alloy came in, reviewed the mill certs, and within a week had us on 6005A-T61 with a new supplier. Scrap rate dropped from 14% to under 2% in one production run.

We were spec'ing 5052-H32 for a draw-and-iron line that was really asking for 5182-O. The formability failures were costing us $80K a quarter in tooling wear and scrap. The Specification Matrix Alloy delivered paid for the entire engagement in the first month.

Retooling an extrusion line for an automotive lightweighting program — we had three candidate alloys and no clear winner. Alloy ran the mechanical analysis, validated our temper assumptions, and had us on 6082-T651 with documented test data before we committed to tooling. Saved us a $200K tooling mistake.
