Bimetallic Aluminum DT4 Clad Plate: Engineered Composite for Electromagnetic and Structural Applications
Bimetallic Aluminum DT4 Clad Plate from Baoji City ShenAo Metal Materials delivers exactly that. Manufactured through advanced explosive cladding technology, our composite plate metallurgically bonds electromagnetic pure iron (DT4) with aluminum to create an atomic-level union. You get exceptional bond shear strength of ≥60-80 MPa, magnetic induction exceeding 1.5T, and electrical conductivity above 60% IACS. This proven solution achieves 30-50% weight reduction compared to solid iron plates while maintaining structural integrity under extreme thermal cycling.
What Makes This Composite Material Different?
This clad plate solves a critical engineering challenge you face every day: joining dissimilar metals without compromising performance.
Traditional mechanical fasteners create interfacial resistance and galvanic corrosion. Welding aluminum to steel? Nearly impossible without defects.
Our product eliminates these headaches entirely.
The DT4 layer brings superior magnetic permeability for electromagnetic applications. The aluminum side delivers lightweight structure and excellent conductivity. Between them lies a metallurgical bond stronger than most adhesives or mechanical joints.
You can machine it, drill it, and form it like standard plate material. No special handling required for most operations.

Where You'll Use This Material?
Electrical Distribution Systems
When you're planning transport bars or conveyance boards, weight and conductivity matter. The aluminum center carries tall streams proficiently whereas minimizing voltage drop. The DT4 layer gives attractive protecting where needed.
Electromagnetic Component Manufacturing
Need components for transformers, inductors, or attractive sensors? The DT4 side offers moo coercive drive and tall attractive acceptance. The aluminum backing gives auxiliary back and warm dissipation.
Transition Joints in Mixed-Metal Assemblies
You can't weld aluminum to steel dependably. But you can weld aluminum to our aluminum side, and steel to our DT4 side. This makes consistent moves in complex gatherings where diverse fabric properties are required in distinctive zones.
Shielding Applications
Electromagnetic impedances is all over. This composite gives you attractive protecting on one side and lightweight structure on the other. Idealize for walled in areas, boards, and defensive boundaries.

Frequently Asked Questions
Can this fabric be welded?
Yes. You can weld utilizing TIG, MIG, or laser strategies. The aluminum side takes after standard aluminum welding parameters. The DT4 side welds like mellow steel. Fair maintain a strategic distance from welding over the bond interface.
What happens at tall working temperatures?
The metallurgical bond remains steady up to 300°C. Past this point, intermetallic compounds may start shaping at the interface. For most mechanical applications, this temperature ceiling gives adequate security margin.
How does it compare to plated materials?
Unlike lean surface plating, our clad plate highlights a considerable layer of each metal. You can machine, crush, and shape it without uncovering a base fabric. The bond won't peel or delaminate beneath mechanical stress.
What thickness proportions are available?
Standard arrangements extend from 20:80 to 50:50 (DT4:aluminum by thickness). We customize proportions based on whether you prioritize attractive properties or lightweight conductivity.
Does it meet worldwide standards?
Our fabricating handle adjusts with ASTM B898 for clad metal items. We give fabric certificates with each shipment archiving chemical composition, bond quality, and mechanical properties.
Is it cost-effective for littler projects?
Material fetched sits between unadulterated aluminum and strong DT4 plate. Your genuine reserve funds come from killing joint disappointments, diminishing framework weight, and amplifying hardware benefit life. Indeed modest-sized establishments see ROI inside the to begin with upkeep cycle.
