Read the archived 5005-H34 black anodized aluminum sheet with limits for color, sunlight, heat, chemicals, forming, testing, and current verification. This resource is for manufacturers evaluating custom nameplates, labels, overlays, or related identification components. Use it to prepare your project questions, then talk with our team about the requirements that apply to your part.
The Lawrence & Frederick black anodized aluminum document in this resource is a two-page supplier reference for material identified as 5005-H34, product code 004MX. It records a historical construction and several important limitations. It is not a current certificate, a purchase specification for every black anodized nameplate, or evidence that the same product remains available unchanged.
Use the document to ask better questions about a proposed metal nameplate. Before release, obtain current supplier literature and confirm alloy, temper, thickness, finish, coating process, color target, intended environment, and downstream manufacturing compatibility. Customer drawings and present purchase requirements take precedence over this archived sheet.
The document describes mill-finish aluminum that was sulfuric-acid anodized, immersion dyed black, and sealed. The supplier lists alloy 5005, temper H34, and thicknesses from .012 through .063 inch. It refers to Lawrence & Frederick designation LFR-5005004MX and marks the document as Revision 1. Those identifiers should remain attached to any historical value copied into a project record.
A material family is not a finished part. Printing, imaging, etching, cutting, forming, holes, adhesives, protective layers, and handling can change the relevant behavior. Record both the incoming sheet identity and the complete nameplate construction proposed for the order.
Alloy describes composition; temper describes processing condition; thickness affects stiffness and forming; anodizing and dyeing describe surface treatment. Replacing one item with a similar-looking option can alter fabrication or appearance. A purchase description should name each property rather than relying on “black aluminum.”
Also distinguish the decorative face from the back and edges. A two-sided appearance requirement, protective mask, grain direction, or edge-color expectation should be written before material is ordered, because those details affect sourcing and inspection.
If a project also uses shaping or holes, coordinate the material with embossing and forming and die and digital cutting. Do not assume every gauge responds identically to a bend, embossment, or tight corner.
The source states that the sulfuric-acid anodic coating met MIL-A-8625 Type II, Class 2 and gives a nominal coating weight of 9.5 milligrams per square inch. That is a dated supplier statement about the referenced material, not a current program approval. Specifications can be revised, superseded, or invoked with additional drawing requirements.
If a customer requires a military, industry, or company specification, obtain the current controlled document and identify the applicable type, class, test method, acceptance criteria, and required evidence. The order record should say whether compliance is based on a supplier certificate, independent test, first-article report, or another approved source. A material data sheet alone should not be relabeled as a current certificate.
“Black” can vary with alloy, base finish, anodic structure, dye, seal, thickness, lot, viewing angle, and lighting. Define whether a visual range, physical sample, or instrumental color tolerance controls acceptance. Also state which side and areas are cosmetic and whether holes or cut edges have separate appearance expectations.
Printed graphics add another color system over the anodized surface. Review ink opacity, contrast, cure, adhesion, and registration through a representative sample. The screen printing page can help frame process questions, but the approved sample and written acceptance criteria govern the specific result.
The Lawrence & Frederick document warns that black dye may fade and says the supplier did not recommend the product for outdoor use in direct sunlight. It also warns that frequent or continuous exposure above 200 degrees Fahrenheit may cause color loss, yellowing, or microcrazing. These cautions must remain visible when the material is evaluated.
Do not reverse those statements into a durability claim. Document actual sunlight, heat source, peak and sustained temperature, thermal cycling, service duration, and acceptable color change. If outdoor or elevated-temperature use is required, ask for a current alternative and evidence designed for that environment. Test the finished construction, not only the incoming sheet.
The source cautions against strong alkalis and acids. A project profile should name process fluids, cleaners, disinfectants, fuels, oils, splash frequency, contact time, concentration when known, and whether exposure reaches edges or mounting interfaces. General phrases such as “chemical resistant” do not define a test.
Maintenance instructions should be approved for the finished image and attachment as well as the anodized metal. The guide on cleaning metal nameplates explains why the least aggressive approved method and a test area are preferable to universal solvent recipes.
Cutting can expose bare edges. Forming can alter surface appearance at a bend. Printing and curing add their own process history. Adhesive lamination can introduce heat, pressure, stiffness, and liner considerations. A flat material coupon therefore cannot qualify every converted feature.
Mark critical cosmetic zones, bend direction, grain direction when relevant, hole locations, edge requirements, and flatness on the drawing. For adhesive mounting, confirm the back surface and planned bonding construction with current data. For mechanical attachment, specify hole size, position, and hardware interfaces.
Protect cosmetic surfaces from scratches, fingerprints, incompatible packaging, moisture, and mixed lots. Use current supplier storage guidance rather than inventing a shelf interval from the revision date. Incoming records should maintain product identity and lot traceability at the level required by the customer.
After conversion, package parts so faces do not rub and finished edges do not damage adjacent pieces. If the order includes multiple coordinated items, label sets may help organize release and packaging, while each material remains separately traceable.
The released record can include supplier and product identity, current data-sheet revision, alloy, temper, thickness, finish, color standard, process route, artwork revision, finished dimensions, attachment, packaging, inspection plan, and required certificates. State approved alternates explicitly. The quality standards page provides broader context for requirement and verification control.
Do not market the archived 004MX statements as current certifications, universal outdoor suitability, or guaranteed heat performance. Preserve the original limitations and replace historical assumptions with current evidence.
Provide a drawing, finished quantity, annual demand when relevant, alloy or performance requirement, thickness, color reference, artwork, attachment method, application environment, heat and sunlight exposure, chemical contact, and documentation needs. Identify whether the project requires samples or a first-article review.
Share those details through request consultation. U.S. Nameplate can evaluate manufacturing options for the specified part; final material selection depends on current supplier information, representative processing, customer approval, and the released purchase requirements.
