Material characteristics of automobile car ramp

Automobile car ramps need to be made from materials with specific characteristics to ensure durability, safety, and usability. Here are the key material characteristics to consider:

  1. High Load-Bearing Capacity: Car ramps should be made of materials capable of withstanding heavy loads, often supporting thousands of pounds to safely hold a vehicle’s weight. Materials like steel or reinforced composites are popular for their strength.
  2. Durability and Wear Resistance: Ramps experience friction from tires and exposure to various elements. Materials like high-strength steel, aluminum alloys, and some polyureas are resistant to abrasion and long-lasting, which prevents wear over time.
  3. Corrosion Resistance: Since ramps are often used outdoors, the material should resist rust and corrosion to maintain structural integrity. Aluminum and galvanized or powder-coated steel are common for their corrosion resistance.
  4. Impact Resistance: Ramps endure dynamic loads, like the impact of tires when a vehicle drives onto them. Materials with good impact resistance, such as steel and polyurea-coated surfaces, help prevent dents and deformations.
  5. Lightweight Options for Portability: Portable ramps benefit from lightweight materials like aluminum or durable composites, which allow for easier transport without compromising strength.
  6. Anti-Slip Surface: For vehicle traction and user safety, ramps often have textured or treated surfaces. This can include rubberized coatings, polyurea finishes, or built-in tread patterns to minimize slip, especially in wet conditions.
  7. Temperature and Chemical Resistance: Ramps exposed to extreme temperatures (hot or cold) and automotive chemicals need materials that won’t degrade, warp, or become brittle. Metals like steel and aluminum, as well as high-quality composites, perform well in these environments.
  8. Cost-Effectiveness and Maintainability: High-performance materials are balanced with cost considerations. Materials like powder-coated steel are both durable and more affordable than some alternatives, while certain composites or treated woods offer cost-effective solutions for lighter-duty applications.

What is ADI?

ADI（Austempered Ductile Iron） is a ductile iron. Through the austenite graded quenching heat treatment process, the structure of ductile iron is transformed into a mixed structure of austenite and ferrite. It is characterized by high strength, high toughness, and good wear resistance and fatigue resistance. Compared with ordinary ductile iron, ADI material has higher strength and wear resistance, and is relatively light in weight, so it has been widely used in many industrial fields.

ADI Casting Process

The process of manufacturing ADI is mainly divided into two steps:

• Casting ductile iron: First, the ductile iron casting is cast to control the chemical composition (such as the content of elements such as carbon, silicon, and manganese) and casting quality of the casting.
• Austenite step quenching: Ductile iron castings are quenched in the austenite temperature range and then kept warm to control the microstructure transformation. Through this process, ferrite is transformed into bainite, while spheroidal graphite remains in the iron matrix, which gives ADI unique mechanical properties.
