Automotive catalytic converters

Description

1. Key Specifications & Technical Characteristics

• Chemical composition: Cordierite or stainless steel substrate + washcoat containing platinum (Pt), palladium (Pd), and rhodium (Rh) in ratios configurable per application (e.g., 5:1:0.2)

• Purity level: PGM purity ≥99.95%; substrate thermal shock resistance up to 1,050°C

• Physical characteristics: Monolithic honeycomb structure; cell density 400–600 CPSI; oval/round form; bulk density 0.6–0.8 g/cm³; color gray-metallic

• Packaging options: Individual foil-bag sealing + ESD foam insert; master cartons 20 units; export wooden crates on request

• Shelf life: 10 years in dry, non-corrosive storage below 40°C

2. Core Industrial Applications

• Primary industries: Automotive OEM (passenger cars & HD trucks), aftermarket exhaust system manufacturers, commercial fleet retrofitters

• Operational use cases: Direct-fit replacement for Euro 5/6 vehicles; universal weld-in units for custom exhausts; closed-coupled converters for turbocharged engines

• Performance advantage: Lower light-off temperature (250°C vs. 320°C industry standard) reduces cold-start emissions by 40%

• Cost advantage: Optimized PGM dosing reduces precious metal cost by 12–15% per unit while maintaining conversion efficiency >98%

3. Competitive Advantages

• Quality consistency: ISO/TS 16949-certified production with 100% inline lambda cross-check and SEM-EDX washcoat uniformity mapping

• Supply reliability: Three redundant manufacturing sites (EU, NA, SEA) ensuring <5% volume variability year-round

• Logistics capability: 48-hour dispatch from regional hubs; hazardous material certified shipping (ADR/RID)

• Price competitiveness: Direct PGM sourcing from LBMA refiners eliminates intermediary markup

• Sustainability: 95% recyclability of substrate and PGM; certified carbon-neutral production line since 2022

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 500 units (mixed SKUs allowed)

• Bulk 20MT capacity: Approx. 3,800 units (based on 5.2kg avg. weight per converter)

• Loading capacity per 20FT container: 24 pallets – 4,200 units (stacked)
