Although titanium is known for its strength and durability. certain conditions such as high pressure. extreme temperatures. or blunt force may cause titanium to crack or fracture. Titanium becomes more brittle at very low and high temperatures.

Heat Deflection Temperature (HDT) of polypropylene typically ranges from 100°C to 150°C, depending on its crystallinity and the presence of any fillers. This value is a key factor in determining the maximum service temperature of the material under load. HDT is critical for applications where polypropylene components are subject to both heat and mechanical stress, as it indicates the temperature at which the material will begin to deform. Enhancements to improve HDT include copolymerization and the addition of reinforcing fibers or fillers. Understanding the HDT is crucial for engineers and designers when selecting materials for parts that will experience elevated temperatures, ensuring durability and performance of the final product.

There is no doubt that electric cars are typically heavier than gasoline cars. because of the battery weight. Even so. the weight of the battery is usually distributed more evenly throughout the vehicle. which can actually improve handling and stability. Electric vehicles are currently being improved in terms of battery technology and weight reductions in the future.
