On the Differences in Raw Materials for Control Arms

Stamped Steel（冲压钢板）:

Most common in mass-produced vehicles. Cost-effective but heavier.

用于大多数量产车，成本低但较重。

Forged Steel（锻造钢）:

Higher strength and durability, often used in performance or heavy-duty applications.

强度更高，常用于性能车型或重型车辆。

2. Aluminum（铝合金）

Cast Aluminum（铸铝）:

Lighter weight, improves suspension responsiveness and fuel efficiency. Prone to corrosion in harsh conditions.

重量轻，提升悬挂响应和燃油经济性，但恶劣环境下易腐蚀。

Forged Aluminum（锻造铝）:

Stronger than cast aluminum, used in high-performance or luxury vehicles.

比铸铝强度高，用于高性能或豪华车型。

3. Composite Materials（复合材料）

Carbon Fiber Reinforced Polymer (CFRP) 碳纤维增强复合材料:

Extremely light and strong, but expensive. Primarily used in racing or ultra-high-end cars.

极轻且高强度，但成本高昂，多见于赛车或顶级超跑。

Polymer Hybrids（高分子复合材料）:

Emerging technology, balancing weight, cost, and durability.

新兴技术，平衡重量、成本与耐久性。

Key Differences（核心区别）

Weight（重量）: Aluminum > Steel > Composites (Lightest)

Cost（成本）: Steel < Aluminum < Composites (Most Expensive)

Strength（强度）: Forged Metals > Stamped Metals > Composites (Context-Dependent)

Application（应用）:

Steel: Economy and standard vehicles.

Aluminum: Luxury, performance, and fuel-efficient models.

Composites: Niche high-performance or experimental applications.
