Product Introduction

The aluminum alloy wiper arm is specially designed for automobiles, rail transit and industrial equipment. It is made of high-strength aluminum alloy and processed by precise CNC technology to meet the core requirements of lightweight, corrosion resistance and long service life. We support customized development based on customer drawings or parameters, adapting to various vehicle models and special scenarios. We provide a one-stop solution from prototype verification to mass delivery, facilitating the performance upgrade of the wiper system.

Product Parameter

Product Name: Automotive Aluminum Alloy Wiper Arm

The product material is 6061-T6/7075 aviation aluminum

Product specifications support non-standard customization

The product processing method is CNC precision processing

Surface treatment: Hard anodizing (film thickness 20-25μm) or electrophoretic coating

Product Feature And Application

High-strength lightweight

It adopts 6061-T6/7075 aviation aluminum material, with a tensile strength of ≥310 MPa. Compared with traditional steel wiper arms, its weight is reduced by 40%-50%, which reduces the motor load and extends the service life.

Precision CNC process

Five-axis CNC machining with a tolerance control of ±0.05mm ensures precise matching with the wiper motor and connecting rod mechanism, eliminating vibration and abnormal noise.

Weather resistance and corrosion resistance

Hard anodized surface (film thickness 20-25μm) or electrophoretic coating, passed 1000-hour neutral salt spray test (GB/T 10125), suitable for high humidity, acid rain, deicing agent environment.

Customized design compatibility

Supports adaptation to mainstream interfaces (U-shaped hooks, direct insertion type), pressure adjustment mechanisms and hidden wiper arm designs, meeting personalized styling and functional requirements.

Rapid delivery capability

CNC technology does not require mold opening. Samples can be delivered within 3 to 7 days, and small-batch orders can be completed within 10 days. It can flexibly respond to urgent demands.

Application scenarios

Passenger vehicles: Front and rear windshield wiper systems for sedans and SUVs.

FAQ

Q1: Is the aluminum alloy wiper arm prone to deformation or breakage?

A: It adopts T6 heat treatment process and reinforcing rib structure design, with a bending strength of ≥280 MPa. After 500,000 fatigue tests, there is no deformation, and its service life far exceeds that of traditional steel arms.

Q2: Can it be compatible with the original vehicle's wiper motor?

A: Support customizing and adapting the arm body and connecting parts according to the original vehicle motor torque and interface type to ensure seamless matching during installation.

Q3: Will the surface treatment fade or peel off?

A: The hard anodic oxide layer has a high bonding strength with the substrate and has passed the 1000-hour QUV ultraviolet aging test without any fading or peeling.

Q4: What are the customization cycle and minimum order quantity (MOQ)?

A: CNC process without MOQ, minimum order quantity: 1 piece. 500 pieces of MOQ die-casting process. The sample cycle is 3 to 10 days, and mass production orders are delivered within 10 to 20 days.

Q5: How to deal with extremely low-temperature environments?

A: The material has excellent low-temperature toughness, with an impact energy of ≥15J at -40℃ (GB/T 229). When used in combination with special low-temperature grease, it ensures smooth operation.

Q6: Is the price higher than that of traditional steel wiper arms?

A: The unit cost is slightly higher, but the lightweight design reduces motor energy consumption and extends its lifespan by 50% to 100%, making it more cost-effective for long-term use.

Q7: Does it support special function designs (such as heating and deicing)?

A: It can integrate electric heating wire channels or reserve installation positions for heating elements to meet the requirements of vehicles in cold regions.
