2033 알루미늄 합금

2033 aluminum alloy is a 2000 series free-machining aluminum grade designed as a lead-free, eco-friendly alternative to traditional 2011. Alloyed primarily with copper, bismuth, and tin instead of lead, 2033 delivers exceptional chip-breaking properties and superior surface finishes in high-speed CNC and screw-machine operations, making it the preferred choice for RoHS and REACH compliant precision manufacturing. Linsy supplies 2033 aluminum bar, tube, and sheet in tempers T3 and T6, with custom sizes, cut-to-length options, and MTC reports available.

What Is 2033 Aluminum Alloy?

2033 aluminum alloy is a 2000 series wrought aluminum grade specifically engineered as a lead-free, eco-friendly free-machining alternative to 2011 aluminum. Instead of lead (Pb), 2033 achieves its machinability through strategic additions of bismuth (Bi) and tin (Sn), combined with a copper (Cu) and magnesium (Mg) base. This lead-free formulation allows 2033 to meet RoHS and REACH environmental compliance requirements while delivering machinability comparable to leaded free-machining grades — producing short, brittle chips and excellent surface finishes in high-speed CNC turning, drilling, and screw-machine operations.

2033 is designed for B2B manufacturers who require both precision machinability and environmental compliance. It is typically supplied in T3 temper (cold-worked and naturally aged) for optimal machinability and T6 temper (solution heat-treated and artificially aged) for higher strength. Its primary product forms are bar, tube, and sheet/coil — the shapes most commonly demanded by precision component manufacturers for automotive, electronics, and industrial threaded-parts production.

Temper Selection Guide — 2033 T3 vs T6

성질 Condition 최상의 대상 Key Trade-off
2033-T3 Cold-worked, naturally aged Maximum machinability, best chip-breaking, tight-tolerance CNC turning and drilling Slightly lower strength than T6
2033-T6 열처리, 인공 숙성 솔루션 Higher strength and hardness, structural threaded parts, load-bearing precision components Slightly reduced machinability compared to T3

Key Characteristics of 2033 Aluminum

Lead-Free, Eco-Friendly Machinability

2033 replaces lead (Pb) with bismuth (Bi) and tin (Sn) to achieve free-machining performance. This lead-free composition enables full RoHS and REACH compliance — a critical requirement for precision components exported to EU and North American markets where leaded alloys face increasing regulatory restriction.

Exceptional Chip Control

During high-speed CNC turning, drilling, and screw-machine operations, 2033 produces small, brittle, and easily evacuated chips. This reduces tool clogging, minimizes machine downtime for chip clearance, and improves surface finish consistency across high-volume production runs.

High Mechanical Strength

2033 delivers ultimate tensile strength above 360 MPa in T3 temper and higher in T6 temper. Yield strength exceeds 280 MPa — placing it above many 6000 series alloys in mechanical performance while retaining its free-machining advantage.

Superior Surface Finish

2033 consistently produces a bright, smooth surface finish directly from the machine tool. This reduces or eliminates the need for secondary polishing operations, saving time and cost in precision component manufacturing.

용접성

Like most 2000 series aluminum alloys, 2033 is not recommended for fusion welding. For applications requiring both machinability and weldability, consider 6000 series alloys. Mechanical joining methods are preferred for 2033 components.

Common Applications of 2033 Aluminum

  • Precision Automotive Components: Fuel system connectors, brake system fittings, sensor housings, and threaded fasteners requiring RoHS compliance and high-volume machinability.
  • 전자 하드웨어: Connector bodies, terminal pins, heat-sink inserts, and precision spacers for consumer and industrial electronics.
  • Complex Threaded Parts: Bolts, screws, nuts, and threaded inserts produced on automatic screw machines — where chip-breaking and surface finish directly affect production speed and scrap rate.
  • General Precision Machining: Instrument components, pneumatic fittings, valve bodies, and hydraulic connector parts for regulated industries.

Processing & Surface Finish Notes

  • CNC Machining: 2033 is optimized for high-speed automatic lathe, CNC turning, drilling, and screw-machine operations. Use carbide tooling at moderate-to-high spindle speeds with light-to-moderate feed rates for best chip control and surface finish.
  • Cutting Fluids: Standard aluminum-cutting coolants are suitable. No special fluid requirements for lead-free operations.
  • Surface Finishing: Anodizing, polishing, and mill finish are supported. Note that anodized appearance may differ from 6000 series alloys due to higher copper content.
  • 용접: Not recommended for 2033. The high copper content and free-machining additions cause hot cracking and porosity in fusion welds.
  • 형성성: Limited cold formability — 2033 is designed for machining, not forming or bending operations.
