I. Product Overview

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. dedicatedly offers premium precision aluminum material solutions for global industrial buyers. Our high-grade series includes 3003 Alloy Precision Aluminum Coils, 4343/3003/4343 Clad Aluminum Strips, and 4005/3003 Bi-metal Multi-channel Aluminum Pipes. Specially developed for automotive radiators, HVAC condensers, industrial heat exchangers, and fluid piping, these materials deliver outstanding corrosion resistance, maximum thermal conductivity, and flawless brazing results. 

II. Industry Challenges & Causes

• Problem: Pitting Corrosion and Hazardous Leakage in Thermal Systems.

  Cause: Insufficient Voids Protection. Standard single-layer aluminum quickly degrades when exposed to aggressive cooling agents or harsh environments.

• Problem: Poor Bonding Quality during the Core Brazing Process.

  Cause: Absence of High-Grade Cladding Layers. Strips without a precise filler layer (such as the 4343 cladding layer) fail to form a homogeneous metallurgic joint under high temperatures. 

• Problem: Tube Failure and Cracking under High Working Pressures.

  Cause: Microscopic Wall Variations. Uneven grain structure weakens the piping, making it vulnerable to fatigue under cyclic pressure from modern refrigerants.

III. Our Solution

• Multi-Layer Clad Anti-Corrosion Technology: We supply the 4343/3003/4343 clad aluminum strips, utilizing the sacrifical cladding layer to prevent pitting and drastically prolong service life. 

   

• Ultra-Precise Fluid Transfer Dimensions: Our Φ25mm × 1.5mm aluminum pipes are made from advanced 4005/3003 alloys, optimizing wall uniformity for robust burst pressure resistance. 

• Optimized Coiling Specifications: Coils and strips are available with standard inner diameters (ID: 500mm / 200mm) to guarantee seamless integration with automatic high-speed stamping and uncoiling machines. 

   

• Honest and Traceable Weight Tracking: Foils are packed at approx. 40 kg per roll for easy manual handling, with the final contract amount determined strictly by actual certified scales data.

V. How To Choose (Selection Guide)

1. Match with the Brazing Furnace Setup: For comprehensive vacuum or controlled atmosphere brazing (CAB), select the 4343/3003/4343 clad strips which already feature the ideal built-in braze-alloy skin. 

    

2. Verify Structure Dimensions: With widths ranging from 16mm to 38mm and thickness down to 0.1mm, choose the precise geometry required for your micro-channels, fins, or header plates. 

    

3. Optimize Shipping Bulk: For large engineering pipelines, purchasing our 4-meter straight aluminum pipes (minimum order 400 pipes) minimizes field-cutting wastage and fits perfectly in containers. 

    

VI. FAQ

• Q: How is the final price calculated if weight varies?

  A: Our rolls are packed at an average weight of 40 kg. Per our transparent commercial terms, the final total price will be fully adjusted and verified based on the actual measured weight before delivery. 

• Q: What are the primary commercial terms and shipment restrictions?

  A: We deliver within 30 days after receiving the down payment via FOB Shanghai. Transshipment is allowed, but partial shipments are not allowed to keep your material arrivals synchronized.
