2. Material selection

2.1 Cast iron material

Cast iron is one of the common materials for adjustable dumbbells, with the following characteristics:

Cost advantage: The production cost of adjustable dumbbells made of cast iron is relatively low, which makes it highly cost-effective in the market. For example, some mid- and low-end brands of Cast Iron Adjustable Dumbbells have a price range of 150-300 yuan, which can meet the needs of consumers with limited budgets.

Weight stability: Cast iron has a high density and can provide stable weight distribution to ensure the balance of dumbbells during use. This helps fitness enthusiasts better control the center of gravity of the dumbbells when performing various training movements, reducing shaking or instability caused by uneven weight distribution.

Durability: Cast iron has good wear resistance and corrosion resistance, and has a long service life under normal use and maintenance. According to market research, the average service life of cast iron adjustable dumbbells can reach 5-8 years, which is significantly more durable than some other materials.

2.2 Steel Material

Steel adjustable dumbbells have unique advantages in performance and quality:

High strength and sturdiness: Dumbbells made of steel have higher strength and sturdiness, and can withstand heavier weights and more frequent use. This is very important for intermediate and advanced fitness enthusiasts, because they usually need to use heavier dumbbells for training, and steel dumbbells can better meet their needs. For example, in some professional fitness clubs, steel dumbbells are widely used, which can withstand weights of up to 50-100 kg and are not easy to deform or damage.

Higher precision: Steel dumbbells can achieve more precise weight control and dimensional accuracy during the production process. This means that the weight error of the dumbbells is smaller, which can provide fitness enthusiasts with more accurate training loads. According to quality inspection data, the weight error of steel dumbbells is usually controlled within ±1%, while the weight error of cast iron dumbbells may be around ±3%. This higher precision is very important for fitness enthusiasts when performing precise strength training and muscle building training.

Appearance and texture: Steel dumbbells usually have better appearance and texture, with more refined surface treatment, which can provide a more comfortable grip and visual effect. Some high-end brands of steel dumbbells use special coating or plating technology, which not only increases the beauty of the dumbbells, but also further improves their corrosion resistance and wear resistance. For example, the "Power Pioneer" brand steel dumbbells use anti-rust coating and frosting treatment, which is not only stylish in appearance, but also comfortable in hand, and is deeply loved by consumers.

Market share: Steel adjustable dumbbells occupy about 30% of the market share. Although its market share is relatively small compared to cast iron dumbbells, it is mainly concentrated in the mid-to-high-end market and is favored by professional fitness enthusiasts and consumers with high quality requirements.
