While inflation over the decades has reduced the value of $1 million, having that amount in your retirement account is still a great goal to strive for. It's still far more than the $87,000 the average American household has set aside for retirement.

Upping your wealth-building game comes down to finding great companies, investing in them, and then letting years of growth compound and do the heavy financial lifting for you.

Industrials are a great place to look. These four remarkable companies help build (and rebuild) the modern world. Consider buying them. They can bring you closer to a bright financial future as part of a diversified stock portfolio.

1. Tesla

Electric vehicles (EVs) have gone from a niche product to an entire industry, and could eventually overtake gas engines as the primary technology in automotive. Tesla (TSLA -1.11%) played a massive role in making this happen, and the stock rewarded shareholders with life-changing returns over the past decade. It wasn't always easy, but today, Tesla is a profitable company with over $95 billion in annual sales.

The EV giant delivered over 484,000 vehicles in the fourth quarter, while U.S. competitors like Ford Motor Company are struggling to grow their production numbers. According to J.D. Power, less than 1% of vehicles in America are electric. That leaves a long runway for Tesla to continue taking market share over the coming decades. That's not including Tesla selling EVs globally and having multiple other businesses, including artificial intelligence and energy storage.

2. Caterpillar

Construction never stops, and the constant need to move large amounts of rock and earth has made Caterpillar (CAT 1.59%) a remarkable investment that's beaten the broader market for years. Drive by any construction site, and you'll probably spot the company's famous Caterpillar yellow machinery. Caterpillar has become a diversified business that makes money by selling machines and financing and servicing them.

Caterpillar is a cyclical stock, meaning it's sensitive to economic ups and downs. While not every cyclical business manages itself well enough to endure the volatility, Caterpillar's ability to pay and raise its shareholder dividend through multiple recessions, a streak at 30 years and counting, shows that it can. An endless need for worldwide construction and commodity mining should ensure years of robust demand for Caterpillar's machines.

3. Illinois Tool Works

Diversity can help an industrial business get through the economic volatility that industrial companies face. Illinois Tool Works (ITW 0.05%) has mastered this. The company is a collection of smaller (but very lucrative) businesses in end markets like automotive, food and beverage, materials, construction, testing, welding, and more. When one segment slumps, another is usually doing well. Illinois Tool Works has grown enough to raise its dividend for 60 consecutive years and trounce the S&P 500 simultaneously.

Illinois Tool Works is transitioning from a phase of being focused on efficiency, raising margins, and divesting some less profitable assets to a more aggressive approach that could see more acquisitions in the future. Management is targeting 9% to 10% annualized earnings growth for the remainder of the decade. The company's long track record means investors should feel optimistic that the stock will continue providing steady returns that compound into significant wealth over time.

4. Albemarle

Lithium is a core material for everything with batteries, which sets up Albemarle (ALB 1.65%) for a bright future. It mines and refines lithium, as well as other specialty materials.

A company like Albemarle that sells a commodity can be very volatile. For example, lithium prices have decreased over the past year, which has pressured Albemarle's business. However, a great company can navigate challenging waters, and Albemarle has paid and raised its dividend for 29 consecutive years, a testament to its resilience.

Since commodity prices fluctuate, investors will likely experience ups and downs while holding Albemarle stock. But there is a clear path to long-term growth. The company is developing mines worldwide to expand its lithium output. It believes capacity could triple by 2030 to as much as 650 KTPA (thousand tonnes per annum). Given the expected multidecade transition to electric vehicles, Albemarle's business should remain strong for years.
