CMMC Level 2 Certified Alloy Supplier for Aerospace and Defense
Altemp Alloys is a CMMC Level 2 certified alloy supplier serving the aerospace and defense industries from our 24,000-sq.-ft. facility. facility in Orange County, California. Since 1979, we have built our reputation on supplying high-temperature metals and exotic alloys to programs that protect our armed forces and keep aircraft operational. Our CMMC certification means that the same standard of precision we bring to alloy sourcing now extends to how we handle your controlled unclassified information (CUI).
For DoD contractors and prime aerospace manufacturers, choosing a CMMC certified alloy supplier is no longer optional. With the Department of Defense phasing CMMC requirements into contracts beginning November 2025, every link in your supply chain must meet the cybersecurity standard specified in the solicitation. At Altemp Alloys, we made the investment early to protect your data and keep your programs on schedule.
Why Aerospace and Defense Buyers Need a CMMC Certified Nickel & Alloy Supplier
Aerospace and defense programs generate large volumes of controlled technical data. Engineering drawings, AMS material specifications, heat lot traceability documents, and order-specific processing instructions all contain information that the DoD classifies as CUI. Every time that data moves from a prime contractor to a material supplier, it must be handled in a secure environment.
A CMMC certified nickel and alloy supplier like Altemp Alloys gives you confidence that your program data stays protected from the moment you send a request for quote through final shipment. Our nickel-based alloys, including Inconel 625, Inconel 718, and Hastelloy X, are among the most commonly specified materials for jet engines, gas turbines, and military vehicles. The data tied to these orders often falls under CUI designations.
Without a CMMC certified alloy supplier in your chain, you carry the cybersecurity risk yourself. Prime contractors that flow CUI down to noncompliant suppliers can face contract termination, lost bidding eligibility, and potential legal consequences. Choosing us removes that exposure.
Our location in Orange County gives us easy access to major freeways, airports, and seaports for efficient distribution. For over four decades, we have served as a trusted link in the aerospace and defense supply chain, and our CMMC Level 2 Certification strengthens that position.
What Is CMMC Level 2 and Why Does It Matter for Your Supply Chain?
The Cybersecurity Maturity Model Certification (CMMC) is a program created by the U.S. Department of Defense to protect sensitive government information across the defense industrial base. It establishes a unified cybersecurity standard that every contractor and subcontractor handling CUI must meet before they can be awarded a DoD contract.
CMMC Level 2 is the compliance tier that applies to most defense contractors and their suppliers. It requires full implementation of all 110 security controls from NIST SP 800-171, covering 14 distinct cybersecurity domains. These controls govern how organizations manage access to sensitive data, monitor their networks, respond to incidents, and maintain the integrity of the information entrusted to them.
This is the level the DoD has designated for organizations that process, store, or transmit controlled unclassified information. That includes technical drawings, material specifications, contract data, and other program-critical files that flow between prime contractors and their suppliers every day.
For procurement teams vetting their supply chain, a supplier's CMMC status is now a qualifying factor. If a subcontractor or material supplier cannot demonstrate compliance at the required level, it puts the entire contract at risk. Prime contractors are responsible for verifying that their suppliers hold the appropriate compliance before sharing CUI or awarding subcontracts.

How Altemp Alloys Earned CMMC Level 2 Certification
Earning CMMC Level 2 Certification required a disciplined and company-wide effort. We conducted a thorough assessment of our IT infrastructure, implemented the full set of NIST SP 800-171 security controls, and documented our practices in a comprehensive System Security Plan (SSP). A Certified Third-Party Assessment Organization (C3PAO) then evaluated our systems, processes, and documentation to verify compliance.
- We actively handle CUI under DoD contract requirements
- DFARS 7012 flowdowns are implemented
- We have a SPRS score (as evidence)
- Controls mapped to NIST SP 800-171
- We’ve already passed real-world compliance scrutiny
This certification builds on our existing commitment to quality and accountability. As an AS9100:D and ISO 9001:2015 certified metals supplier, we already operate under strict quality management systems. CMMC Level 2 extends that rigor to the digital side of our business, ensuring that verified cybersecurity controls protect the technical data, material certifications, and program information our customers share with us.
Our team prepared for this because we understand what is at stake for our customers. When you share material specifications for a jet engine component or controlled technical data for a defense platform, that information deserves the same level of care as the alloys we stock and process.

As a single-source provider, we reduce lead times and simplify your supply chain.
Frequently Asked Questions
How does CMMC Compliance differ from AS9100 or ISO 9001 certification?
AS9100 and ISO 9001 focus on quality management systems, including product consistency, process documentation, and customer satisfaction. CMMC is specifically a cybersecurity certification. It governs how an organization protects sensitive digital information, manages network access, monitors for threats, and responds to security incidents. A supplier can hold AS9100 certification and still lack the cybersecurity controls required by CMMC. As a CMMC Level 2 alloy supplier for aerospace and defense projects, we hold all three certifications, covering quality management and information security.
How long is CMMC Level 2 Certification valid?
A CMMC Level 2 Cerification is valid for three years from the date of the initial C3PAO assessment. During that period, the certified organization must submit an annual affirmation of continued compliance through the Supplier Performance Risk System (SPRS). After three years, a full reassessment by a C3PAO is required to maintain certified status.
